The creation of a Biomedical Engineering
Technology program for the 2020s
Abstract
Many biomedical engineering technology or similarly named programs were spawned in the
early 1970s. These programs, at the two-year college level, were a response to the demand for
technicians to deal with the rapidly expanding base of medical equipment that was being
deployed primarily in hospitals. Although there were many electronics engineering technology
programs at the community college level, it was thought that the need for technicians skilled in
the medical equipment area would be more successfully satisfied through a specific program that
taught the fundamentals of electronics and then concentrated on medical equipment and
electrical safety. Programs were designed to produce graduates that could deal with the
biomedical equipment technology of the day and the needs of the clinical workplace.
During the time that these programs flourished, biomedical technicians would troubleshoot faults
to the part level and replace defective components to affect a repair. However, Moore’s law has
been hard at work for the last five decades and the technology utilized by the medical field has
morphed substantially over the last twenty years in particular. The adoption of digital electronics
technologies to replace analog electronics, the introduction of low cost microcontrollers into
electronic systems, the Internet, wireless networking technologies, medical laser systems, and
innovative medical sensors and imaging techniques has changed the way medical care is
delivered today and the way maintenance and repair of equipment is performed. Furthermore, it
is felt by many that the e-healthcare field is at the cusp of another change that will rapidly
transform the medical device industry and as a result modify noticeably how health care is
provided. The implementation of medical cyber-physical systems will allow for the development
of virtual medical devices that will be deployed in both a clinical setting and in the home.
Presently, engineering technology education at the two-year college level does not produce
technicians with the skill sets needed to install, evaluate, maintain, and up-grade these systems as
they are envisioned in either setting. This paper will discuss the design and impending
implementation of a two-year “biomedical engineering technology” program tailored to meet the
e-healthcare workforce needs of the end of this decade and those required as we move into the
2020s for both clinical sites and home environments.
Introduction
During the early 1970’s, Springfield Technical Community College (STCC), a commuter college
located in the center of Springfield, Massachusetts established a distinct two-year Biomedical
Instrumentation Technology (BMIT) associates in science (AS) degree program. The program
was typical of biomedical technology programs of the time and had the goal of graduating
technicians that could deal with biomedical equipment in a clinical environment. The first year
of the program was similar to the first year of already existing, pervasive, Electronics/Electrical
Engineering Technology (EET) degree programs. The curriculum consisted of the required
general education courses and additional technical courses in the fundamentals of DC and AC
circuits and active semiconductor devices (i.e. analog electronics). During their second year of
study, students took courses in biomedical systems and measuring principles, a “Codes-Laws-
Safety” course, and participated in hospital internships, thereby, differentiating the program from
the classic EET programs of that time period. As the field of electronics technology entered the
Page 26.1513.2
![Page 3: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/3.jpg)
microelectronics era, courses about integrated circuits, microprocessors, and digital logic were
added to the biomedical curriculum to keep up with the rapidly changing technology. As was
typical of that stage in the evolution of electronics, the curriculum was extremely “parts centric”
since biomedical (and electronics) technicians were expected to repair electronics based medical
equipment by troubleshooting faults/problems to the part/device level. This popular program ran
successfully for approximately three decades during which time most of the medical facilities in
western Massachusetts and regions in surrounding states (i.e. middle to north-central Connecticut
and southern Vermont) employed graduates of this department. The program’s reputation was
such that a good number of the students that graduated from the program came from outside of
the school’s service area and then returned home to work after graduation. However, the program
became a victim of its own success when it eventually saturated the local workplace with
graduates during the mid- to late-1990s and was subsequently suspended due to the lack of a
workforce demand for biomedical instrumentation technicians in the college’s immediate service
area.
There have been no active public college, standalone, associate degree, biomedical technology
programs in the service area of Springfield Technical Community College or the central and
western part of the state of Massachusetts, for that matter, for the last fifteen years. During that
period, this author can attest to the fact that to satisfy whatever local demand existed over that
time frame, only a handful of the graduates of the college’s Electronics Systems Engineering
Technology (ESET) program (successor program to college’s legacy EET program) were hired
by local hospitals and medical equipment suppliers and these graduates were subsequently
trained in house by the vendors to deal with the medical industry specific hardware used in
various clinical settings.
Starting in 2011, the college was approached by a biomedical industry group, the Biomedical
Engineering Alliance & Consortium or “Beacon Alliance” located in Hartford, Connecticut. This
group, as illustrated on their web site1, consists of a broad spectrum of members from both the
public and private sectors with an interest in the promotion of the biomedical industry. Their
explicit intentions for contacting STCC were an effort to attempt to convince the college
administration (or at least start a dialogue) of the need to re-institute a biomedical technology or
similar type of degree program and to also add a biomedical device manufacturing track to its
technical programs. Besides the large medical/health sector industry in the college’s service area,
there are presently a large number of medical device manufacturers2 in the so called “New
England’s Knowledge Corridor”3 that is also part of the college’s area of service. A group of
STCC administrators and faculty from the School of Engineering Technology (SET), with
varying amounts of expertise in these areas, was convened to meet with the Beacon Alliance
people. One of the key questions asked by the faculty on the college’s committee was, “what is
the need?” Many on this curriculum “feasibility” committee were not convinced that a definite
need existed for a classic biomedical technician and some even thought that the very name was
misrepresenting what present day technicians in a hospital or clinical environment actually did.
Furthermore, although there was an agreement for the need of a workforce for advanced
manufacturing, the question again comes back to the numbers. Over the course of time, research
by the committee into workforce needs and meaningful conversations with employers yielded
further insight into what might be appropriate in terms of the required skill sets for these areas.
Several more meetings with the Beacon Alliance people and some of their members were held,
Page 26.1513.3
![Page 4: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/4.jpg)
talks with the local Regional Employment Board of Hampden County were held, a visit by many
on the committee to the newly completed (2012) Baystate Medical Center’s $300 million
“Hospital of the Future”4 located in Springfield was conducted, and a great deal of brainstorming
about what might be useful in terms of workforce development took place. It should also be
noted that consideration of the potential “graying” of the incumbent biomedical workforce and
pending retirements was also considered. Some of the committee, including this author, felt that
this proposed initiative presented an opportunity for the faculty to develop a new technical
program that would provide new graduates with the needed skill sets for the biomedical/
healthcare industry that would be relevant well into the next decade. The unanswered questions
were, “who would take on this task” and “where would the necessary funding come from?”
Interestingly and also unexpectedly, during these prolonged deliberations about the pros and
cons of the Beacon Alliance requests, the Massachusetts Life Sciences Center (MLSC)5, a quasi-
public organization charged with administering the ten year $1 billion Life Sciences Initiative
enacted by the Massachusetts Legislature in June 2008, put out a request for proposals at
approximately the same time (2013) for initiatives to enhance the life science’s workforce for the
state of Massachusetts. The college’s Grants Office applied for and received a relatively modest
planning grant to develop curricula and plan out capital equipment and facility needs for three
identified tracks that were related to the biomedical/life sciences industry. The three tracks were
tentatively named: Biomedical Instrumentation Technology, Biomedical Manufacturing
Technology, and Biotechnology. The first two tracks would be for new programs that had been
topics of discussion with the Beacon Alliance for the last two years while the third track involved
a relatively new pre-existing AS degree program6 that would be updated.
Furthermore, one of the faculty members on the SET curriculum feasibility committee already
had a $.5 million National Science Foundation (NSF) Advanced Technology Education (ATE)
grant titled, “Intelligent Infrastructure Systems Education Project”, with its foremost project
goals being curriculum development (including course material and labs) and two-year college
faculty development activities. Today, this technology is better known as the Internet of Things
(IoT) or cyber-physical systems (CPSs) technology. Cyber-physical systems technology refers to
embedded control systems that are “tightly coupled” to the real world and require timing to
perform their function.7 This multi-year ATE grant, awarded at the end of 2010, had allowed this
faculty member the time and resources to research the emerging e-healthcare industry and to
learn how the enabling technologies of cyber-physical systems might profoundly revolutionize
the biomedical instrumentation/device industry. This nascent technology will allow us to change
how we provide healthcare in a clinical setting and transform how we care for our aging
population in their own homes. This awareness of how the healthcare industry was morphing and
an understanding of the characteristics of cyber-physical systems technology would become
quite influential in the development of a curriculum that would prepare biomedical graduates for
the new era of e-healthcare. With the pieces of the biomedical instrumentation puzzle falling into
place and funding from the MLSC planning grant, it was now time to develop and fine-tune the
curricula. This group effort took place over a period of about a year with the most recent draft of
the final curricula solidified during the fall of 2014. The rest of this paper outlines the changes
that are occurring in the healthcare industry to illustrate and rationalize the changing skills
required by technicians for this field, addresses the various technologies used to implement the
changes, relates the effects of cyber-physical system technology on the needed skill sets, and

then chronicles the development of the curricula for the tentatively named “Biomedical
Instrumentation Technology” program. Note that the Biomedical Manufacturing Technology
track will not be addressed in this paper. Lastly, this paper will present an overview of an
additional $1 million in funding recently received from the MLSC for capital costs, as well as,
the final steps needed to bring in the first class of students.
The Dilemma and the Opportunity If one goes to the United States Department of Labor website and does a search on biomedical
engineering technician, one is redirected to medical equipment repairs as the closest occupational
classification match. Under this category, one finds a ten year projection of a yearly 30% growth
in employment8 through the year 2022. This figure certainly seems to indicate that there is a need
for such skills but it really does not tell the entire story. As mentioned earlier in this paper, the
now defunct Biomedical Instrumentation Technology program at STCC as originally conceived
in the early 1970s was “parts centric”. During that era, the unambiguous, part/component centric
aspect of the technology dictated how the technicians in this field were educated. However, since
the early 1970s Moore’s Law has been hard at work and the ball game has changed (see Figure 1
below).
Figure 1 – A depiction of Moore’s Law from 1970 to 2020
Over time, as could be predicted from Moore’s Law, electronic systems have evolved from a
collection of boards, crammed full of components, to systems-on-a-board, to systems-on-a-chip
(SoC) technology9. Today, industry routinely produces integrated circuits (ICs) that contain over
a billion transistors – this coupled with micro- or nano-electromechanical systems (MEMs or
NEMS) technology allows us to design and build complex, highly functional SoCs with on-chip,
high-powered, processing cores. In the biomedical field, all these technologies combined with
microfluidics technology allows for the fabrication of “lab-on-a-chip” type bio-sensor systems.
These technology developments have changed the way that we deal with the vast majority of
electronics based systems. We seldom repair electronic systems (which includes biomedical
equipment) to a part or component level anymore. Hence, for the faculty tasked with program
Page 26.1513.5
![Page 6: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/6.jpg)
development - the dilemma and the opportunity. These realities then beg several questions; Do
we continue to teach topics like biomedical instrumentation the way we had been doing it,
which, to the thinking of some, imparts a good deal of irrelevant skills and information to the
students, or do we take a new approach? Furthermore, have the needed skill sets morphed so
radically over time that the curriculum needs a different emphasis other than purely medical
equipment? Is an interdisciplinary approach that conveys the skills needed to deal with emerging
interdisciplinary technologies the correct tactic? To the first point, this author and others have
been proponents of teaching electronics based technology by means of a more systems oriented
approach for the last decade.10-15
It appears that the debate on this topic (at least in the electronics
engineering technology faculty ranks) is far from over and will continue on for some time to
come. However, the group agreed that for our proposed new biomedical technology curriculum a
systems centric approach will be taken. The second and third points will be addressed shortly
following a quick look at several other drivers of technologic change.
During the last two decades, additional factors have also transformed the way in which most
industry designs/engineers and uses electronic systems. We are at the beginning of the next
evolution in the possible uses and applications of electronics based technology coupled with the
connectivity of the Internet and embedded intelligence. Designers are adding intelligence and
communications links to our electronic/electrical systems in an effort to enhance their efficiency,
functionality, and ability to be reconfigured as needed. As mentioned previously, there are
several industry and popular press names for this phenomena: intelligent infrastructure systems,
the Internet of Things, Cisco’s the Internet of Everything (IoE), IBM’s Smarter Planet, and most
recently, (in scientific circles) cyber-physical systems. If one considers these types of Internet
enabled applications, it is evident that they are becoming both technically and economically
feasible due to the continued convergence of several mature, enabling technologies. Essentially,
through the use of low-cost but powerful networked embedded controllers (also known as
ambient intelligence), complex networked sensors and actuators (i.e. sensor networks), a
ubiquitous high-speed Internet facilitated by wireless data transmission technologies, and
applications specific software we are able to create intelligent infrastructure systems that have
the potential to change almost every aspect of mankind’s interaction with its environment.
Moreover, we will have the ability to efficiently and safely control large scale systems such as:
vehicle (land, air, and sea) transportation systems, power generation, transmission, and
distribution, and many other heretofore intractable applications of control system technology.
Cyber-physical system technology, by necessity, brings together the two worlds of information
technology (IT) (software) and the Internet of Things (IoT) (hardware).16
The understanding of
the theory and operation of wired and wireless networks, embedded controllers and their
interaction with sensors and actuators, data acquisition, and control software will be the required
skills needed to deal with these emerging technology applications. As shown below in Figure 2,
the foundation of the Internet of Things consists of these enabling technologies. A technician that
has to deal with cyber-physical systems or less complex sensor systems for a particular
technology will need to be skilled in the topics indicated in the figure and additionally must
possess knowledge about the particular technology (e.g. biomedical technology, power
transmission technology, vehicular technology, etc.) that the cyber-physical or sensor system is
being deployed within. The model depicted by Figure 2 shows the inter-disciplinary foundational
skills needed by a technician that deals with an “electronics based” technology application.

Figure 2 – The underlying technologies of the Internet of Things (IoT)
Examining the healthcare field reveals that there are a host of applications involving “small
scale” medical cyber-physical systems for humans. Most of the medical sector applications
involve various wearable or implantable physiological sensors and actuators to be deployed on a
human body and used to continuously monitor patient health, enable fast detection of medical
emergencies, and deliver suitable therapies (e.g. pacemakers, insulin pumps, neurostimulators,
etc.) A key technology enabler for this area is wireless body sensor networks (BSNs) a sub-set of
wireless networking. Looking at the overall field of e-healthcare, wireless sensor networks are
poised to revolutionize how we care for the elderly or people with health issues.17
Until now, the medical device industry has been in the business of designing and fabricating
standalone devices to treat patients – diabetes care (insulin pumps), drug delivery systems
(infusion pumps), cardiovascular devices (pacemakers), respiratory devices, etc. This industry is
on the cusp of a rapid transformation. The results of which will be the medical device industry’s
embracement of the potential benefits of embedded software and network connectivity. Instead
of standalone devices, distributed systems that simultaneously monitor and control multiple
aspects of a patient’s physiology are ready to come out of the lab and be deployed for use in the
medical field. This combination of embedded software controlling these devices, networking
connectivity, and the problematic physical dynamics exhibited by the human body makes
modern medical device systems a distinct class of cyber-physical systems – being referred to as
medical CPSs or MCPSs. Recent industry predictions are for rapid market growth (>10% per
year) over the next decade for this emerging technology.18
The traditional clinical scenario can be equated to a classic closed loop control system model.
Medical devices act as sensors and actuators, the patient is the object being controlled (i.e. the
process), and caregivers (medical personnel) are the controllers. MCPSs alter this view by
Page 26.1513.7
![Page 8: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/8.jpg)
introducing additional computational entities into the control system that aid the caregiver in
controlling the patient’s well-being. Figure 3 below shows a conceptual overview of MCPSs in
block diagram form.19
The medical devices used in MCPSs can be placed into two broad groups
based on their purpose in the system – monitoring devices or treatment delivery devices.
Monitoring devices include: oxygen-level (pulse oximeters) sensors, temperature sensors, and
heart-rate monitors that all provide information about a patient’s present physiologic state/status. Treatment delivery devices include: infusion pumps and ventilators which physically actuate
therapy capable of changing the patient’s physiologic state in a positive way. In MCPSs, the
monitoring devices can feed data collected to a decision support or administrative support entity,
each of which serves a distinct and yet complementary purpose in the delivery of the patient’s
healthcare – the data may be transmitted through a network (wirelessly or hard-wired) to these
two entities. Administrative entities such as those represented by the electronic health records
(EHRs) and pharmacy stores icons are used to manage: patient health and treatment information
collected over a period of time. Given the personalized information that they gather, they have
the real potential to provide targeted actuation of treatment based on a more holistic view of the
patient’s health (i.e. considering potential drug interactions or the historic evolution of a patient’s
specific physiologic parameter or medical condition).
Figure 3 – Medical cyber-physical systems: Conceptual overview (Source:
IEEE Proceedings, Volume 100, Number 1, January, 2012
These administrative entities can assist in fulfilling the need for the continuous care of the
medical patient. Continuous gathering of data and the management of it is essential for many of
today’s health issues such as dealing with an aging population (data indicates that this is a world-
wide trend) and the associated rapid rise in the number of individuals with chronic disabling
conditions such as asthma, arthritis, heart disease, hypertension, and diabetes – to name the most
common. Decision support entities can process the data collected and use this processed data to
generate alarms for many medical emergencies that might occur. These alarms are necessary to
allow clinicians to know when the patient’s state of health has deteriorated and what information
Page 26.1513.8
![Page 9: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/9.jpg)
is relevant to treat them. At the present time, most medical devices can only be configured with
alarms that are activated when a threshold is exceeded.20
Research has shown that threshold alarms are unscientific and actually can lead to a decrease in
the quality of care. These alarms only alert a clinician to the fact that a threshold has been
crossed; they fail to provide any physiologic or diagnostic information about the current state of
the patient that might help reveal the underlying cause of the patient’s distress. The offshoot of
this is that medical device alarms need to become “smart”. With smart, targeted alarms that
provide context information about what caused them; caregivers can analyze the information and
use it more appropriately. The caregivers can then use the medical delivery devices to initiate
treatment (see Figure 3). This brings the caregiver into the control loop around the patient as also
shown by the figure. Alternatively, the decision support entities can employ a smart controller
(again, see Figure 3) to analyze the data received from the medical monitoring devices, appraise
the state of the patient’s health, and under computer control automatically begin treatment (e.g.
drug infusion) by issuing commands to medical delivery devices, thereby closing the control
loop. This last scenario outlines the operation of what might be considered a virtual medical
device (VMD).21
In the near future, MCPSs that stream real-time medical information from
different devices and combine it with information from a patient’s health record would most
likely improve the accuracy and usefulness of alarms. These systems could be designed to
automatically suppress irrelevant alarms and provide summaries of the patient’s state, as well as,
predict future trends in the patient’s condition. These MCPSs would act as high accuracy smart
alarms. This is where the networked connectivity of medical devices comes in. MCPSs will
consist of networks of medical devices and computer systems cooperating to provide patient care
– again a “virtual medical device”. VMDs can be brought into the patient care loop by coupling
specific network-connected devices (both monitoring and delivery) with the appropriate clinical
algorithm executing on a computer – a VMD “app” if you will!

At this point, let’s turn our attention to e-healthcare applications in the home. As previously
noted, body sensor networks (BSNs) are a key enabler of this type of technology. BSNs promise
to improve the quality of life through improved health, augmented sensing and actuation for the
disabled, independent living for the elderly, and reduced healthcare costs. Body sensor networks
consist of sensors and actuators that are typically worn on the human body or possibly implanted
in the human body (see Figure 4 above). As previously discussed, body sensors are the essential
elements of what are widely known as wireless body area networks or WBANs. For home
healthcare applications another type of sensor – ambient sensors are also considered to be part of
the overall picture. Body sensors are placed on, in, or around a user’s body for continuous
monitoring of the user’s physiological conditions such as heart rate and temperature. Ambient
sensors are typically used to measure the local environmental conditions. The use of ambient
sensors can be expanded to provide measurements of a person’s vital signs, as well as, other
meaningful information about a person’s movements (the usefulness of this will be touched upon
later). The human body produces many electrical “signals” that can be used by the medical field
to diagnose various medical conditions. Beyond our “vital signs” are brain waves (EEG), heart
signals (EKG or ECG), muscle signals (EMG), and nervous system signals.
We have already touched earlier upon the idea of sensors that analyze a person’s blood chemistry
using MEMs or NEMs based (lab-on-a-chip technology) bio-sensors. In the home environment,
all the sensors are networked and transmit data (via (multihop) wireless networking technology)
to the home “gateway” device (again, see Figure 4). The home gateway device provides a
connection to the Internet which provides connectivity to the health monitoring system. Several
IEEE wireless technologies that can provide this type of in-home connection to a gateway are
IEEE 802.15.4x, IEEE 802.15.5, and IEEE811.15.6. The gateway is connected to the Internet
through the use of either a wireline connection (DSL or Cable) or fiber optic technology or
cellular technology (now, 3G or 4G or future 5G). Of course, the goal is to make the body
sensors and their radio technology as small and as unobtrusive as possible.
Low power Radar sensor technology can be used for monitoring breathing conditions and
identifying potential abnormalities of sleeping people22
. Noncontact vital sign detection has been
demonstrated by researchers all over the world using radar systems. Radar sensing can be
utilized for indoor detection of human falls which allows for timely and accurate reporting of fall
incidents which can become severe if not dealt with in a timely (immediate) manner. Accurate
respiration measurements and monitoring also lends itself to many other important applications
such as: lie detection, psychotherapy, assessment of human physical states, and speech
monitoring. Respiration is a natural human activity; however, it is not uniform but changes in
association with a human’s physical state. Conventional medical monitoring techniques are
mostly based on contact methods and therefore are not as reliable or accurate.
The use of radar technology has also been suggested for gait analysis (i.e. observing how a
person walks) – an evolving medical field with many potential applications. Radar is not blocked
by walls or clothing and therefore these applications are not restricted to a single room
environment. Furthermore, the tracking of a person’s daily movements using this type of
technology is thought to be useful for the diagnosis of Alzheimer's disease23
. More recently,
there have been many experiments performed using very high frequencies (i.e. 100s of GHz) to
implement “remote” (non-contact) physiological sensing. It has been reported that heart rate
Page 26.1513.10
![Page 11: The creation of a Biomedical Engineering Technology ... · biomedical equipment technology of the day and the needs of the clinical workplace. During the time that these programs](https://reader035.vdocuments.net/reader035/viewer/2022070718/5ede0bfaad6a402d66695085/html5/thumbnails/11.jpg)
changes may be detected by focusing an extremely high frequency beam of submillimeter wave
energy on the palm of a human hand – most of these techniques look at the parameter known as
the “reflection coefficient” of human skin to detect subtle changes in the heart beat of a human
subject.
The health issues related to an aging population are very complex. For people over the age of 65,
one of the most serious health care risks is falling. This is the leading cause of death for this age
group! For those that survive a fall, many will suffer hip fractures. Even with successful surgery,
about 40% of those hospitalized for a hip fracture cannot return to independent living, and,
amazingly enough, about 20% will die within a year! Using sensors like radar and/or wearable
accelerometers to detect falls, this age group would have a better prognosis for survival. Care for
people with heart disease is one of the biggest contributors to healthcare spending – at a cost of
$40 billion a year. The use of BSNs and WBANs to monitor patients at a high risk of falls and
those with chronic conditions or diseases can provide improved and more efficient healthcare in
a home environment setting.

Table 1 – Proposed Biomedical Instrumentation Technology curriculum
As can be seen from Table 1, there are traditional general education courses and electives and
technical courses appropriate to the discipline. In the 1st semester, the technical courses consist of
Electronics for Technicians 1 (basic theory of electrical circuits) and Introduction to Biomedical
Devices and Industry (new courses are bolded in the Table) and there is an additional course
dealing with computer applications. In the 2nd
semester, the technical courses are Instrumentation
and Measurement, Electronics for Technicians 2 (basic theory of electronics), and Embedded
Controllers & Lab (all existing courses) and Human Biology 1. In the 3rd
semester, students take
Human Biology 2, Sensors and Data Acquisition (existing course), and Cisco’s – Introduction to
Networking (from the Cisco Academy CCNA curriculum). Finally, in the 4th
semester, both a
physics and chemistry course, and three new course: Biomedical Wireless Data Networks,
Sensors for Biomedical Systems, and Biomedical Systems.
The curriculum gives the students skills in the particular technology (biomedical) through
courses in Human Biology, Biomedical Devices & Industry, Sensors for Biomedical Systems,
and Biomedical Systems. Two courses present the fundamentals of electric circuits and
electronics (in a systems oriented fashion), two courses present instrumentation, measurement,
sensor, and data acquisition theory, one course presents information about computer use and
applications, one course introduces the concepts of computer networking, and one course builds
on several others by presenting material on Biomedical Wireless Data Networks. If one looks
back at Figure 2, it should be evident that the curriculum has captured most of the underlying
technologies of cyber-physical systems. The Biomedical Wireless Data Networks course in the
fourth semester introduces new technology that was not previously considered to be associated
with this technology area. For this reason some additional detail about this course’s content will
be offered here. The course objectives are given below in Table 2.
Biomedical Wireless Data Networks Course Objectives
1. To become familiar with the concept of a wireless electronic communications
system/network
2. To become familiar with the limitations of wireless networks due to various system
impairments
3. To become familiar with basic sub-systems of wireless networks and communications
systems
4. To become familiar with the concept of RF signals, communications frequency bands, and
digital modulation
5. To become familiar with the functions of electronic communications hardware
6. To become familiar with the properties of electromagnetic propagation

7. To become familiar with today’s wireless networking systems
8. To become familiar with typical wireless test and measurement equipment
9. To become familiar with the techniques used to diagnose and evaluate the correct operation
of wireless networks
Table 2 – Course objectives for Biomedical Wireless Data networks
To achieve these course objectives students will be exposed to the fundamental concepts of
wireless communications, present day wireless data networks, wireless technology specific to
biomedical applications, wireless test and measurement equipment, and wireless system
operation evaluation techniques.
Conclusion
It was the feeling of the SET committee that the time was ripe to put together a forward looking
technology program that filled a workforce need. Many of the electronics technology faculty in
New England that were involved in the long running Verizon NextStep Program24,
(of which this
author was one) have felt that “derivative” technologies that are based in electronics systems
technology do not need technicians that are experts in electrical circuits theory or the mundane
knowledge of how to bias the many configurations of a transistor to make an amplifier circuit.
Experts in circuit theory and electronics tend to gravitate towards the fewer and fewer jobs that
require those skills. That lore and detailed knowledge of the field was appropriate when we fixed
systems to the part level. Those days are pretty much over now. Instead, the technician’s task has
morphed to include: new system installation, verification of correct operation, confirmation of
system electrical connections, total replacement of defective systems, and reprogramming and
updating system software. Electronics technology is a tool to be used to create physically
implemented applications that do useful things or tasks for us. If these applications happen to be
in the healthcare arena, we welcome those that keep us healthy and well as we live our lives. The
use of electronic systems, sensors and actuators, embedded controllers, and the connectivity of
the Internet open up a whole new field of possibilities for cyber-physical systems in the e-
healthcare field. Society will embrace these new types of applications that can improve our lives
and keep us in our homes longer. It’s time we started educating technicians to deal with this
technology!
Much like an epilog to a story, it should be revealed that as this paper was being prepared for
submission, the college was notified that its second grant application to the MLSC had been
favorably approved for $1 million to support the capital expenditures needed to proceed with the
implementation of the new programs (i.e. Biomedical Instrumentation & Biomedical
Manufacturing Technology). These capital expenditures include new equipment and renovation
of the space needed to house the new biomedical instrumentation program’s labs. This grant
money is for a two year time period - Fiscal 2015 through Fiscal 2017, so it is planned that we
take in our first classes of students in the Fall of 2016 and have the first graduating class in 2018.
The college’s admissions department will advertise the new programs through the traditional
media sources, we will hold open houses for local high schools, and we will do outreach by
going out to local schools to publicize these new programs. One of the interesting things about
these programs is the fact that young women are typically drawn to the healthcare industry. We
are hopeful that these programs can increase the number of female students in the STEM

disciplines at STCC. There is still, sure to be, some fine tuning to the curriculum to be
accomplished but the committee that put this program together has a great deal of confidence
that its graduates will possess skills that will make them extremely employable in the e-
healthcare industry well into the 2020s.
