ENERGY HARVESTING - MRH

What is energy harvesting?

Energy Harvesting is the process where the energy not used and coming from existing sources (i.e. vibration, repetitive movements, solar energy, wind energy, etc) is captured, stored and used for energy supplying of electronic devices autonomous and wireless.

Why are we talking about harvesters in MRH?

Harvesters offer new possibilities to rehabilitation devices because they are very attractive to replace batteries in low consumption and/or wireless devices.





Advantages:• No maintenance required.• More autonomy• Practice rehabilitation anywhere.• No batteries required.•New functionalities

Disadvantages:• Low power generation.• Complex designs.


Main concepts





CDEI-UPC Previous experience

CDEI has developed several electromagnetic harvesters in transfer of technology projects.The generators are used into power wireless sensors to perform CBM (Condition Based Monitoring) in trains.

Electromagnetic Prototype developed in CDEI.






Energy Harvesters

Vibration-Powered Generators

Thermal-Powered Generators

Piezoelectric

Deformation-Powered Generators








VibrationThe oscillating system is typically a cantilever-beam structure with a mass at the unattached end of the lever.

EoPlex Technologies Ltd. Prototype

DeformationAny force can be converted in electrical energy leveraging the capabilities of piezoelectric materials. Variable forces or impacts applied into piezoelectric elements have been used in human applications.

PIEZOLECTRIC HARVESTERS






ELECTROMAGNETIC HARVESTERSRelative motion between a coil and a magnet causes the induction of an electric current in the coil (Induction Faraday’s law)

ELECTROSTATIC HARVESTERSMechanical forces are employed to do work against the attraction of oppositely charged parts; in effect, such devices are mechanically variable capacitors whose plates are separated by the movement of the source of vibration.






THERMAL HARVESTERSTemperature differences of only a couple of degrees, induce heat to migrate to the cooler region of a thermoelectric system. This heat flow carries electrons with it, thereby generating a current.






Movements done by patients during its rehabilitation process can be a source of energy, using the electromagnetic principle of harvesting.What are the advantages of this proposal?1. The devices developed in the project would have autonomy to acquire, store and send

data. This would offer the possibility of rehabilitation anywhere (with the only requirement of low electric consumption systems).

2. The Power harvesters designed are suitable to be used in other applications and systems with similar conditions. That can result in a very attractive device for companies, as they can open their market to several sectors using energy harvesters.

3. It is an extra value of the rehabilitation devices, making them more versatile without a significant cost increase.

4. Energy harvesting in MRH can be used as a motivation tool (medical experts point motivation of patients as a key point for faster rehabilitations). The device being able to store and show the energy that is being generated by the patient can create a motivation score for them.






Pilot case. Energy harvesting applied to Foot ThrottleIn the mechanical prototype of the foot throttle there is the possibility of replacing the passive force done by the four pistons.

The pistons may produce an equivalent resistant force and necessary energy to supply the electronic system.

The user performs some force at some speed, that are the inputs in our system.

We want to obtain the values of those force and speed, and also position data -

As some electricity is generated, we can estimate the values for the force and speed from the generated current and tension. And the position data is get with a sensor.

Estimated results

Based on different user kinds, and considering mechanical and electrical efficiency of all the device parts, we have estimated the power generation in the two allowed movements.

Even in the worst case, the energy generation can allow feeding basic electronics to acquire data.

Pilot case. Energy harvesting applied to Foot Throttle





The final purpose of this device is to acquire some data that can be used by the therapist. That’s why we want to store, for each exercise, the number of cycles performed, force, speed, position and time. This data is stored in the device and can be read from it or can be sent to the therapist.

The autonomy of this device is the main advantage, so it can be used everywhere.

Business model Customer segments

First approach: end users

• Elder people• Diabetic patients

• Patients• Clients

Secondapproach

• Therapists• Healthcare providers

It is known the decrease in strength (and quality) of lower leg muscles due to diabetes mellitus as well as age effects (elderly). For the former group the ventral (anterior) muscles decrease more rapidly than the dorsal muscles. For elderly the strength of (leg) muscles is overall decreasing as a function of age. Therefore a rehabilitation device for lower limb at home can involve a higher quality of life for those people.

Patients would be associated to rehabilitation, while clients would be associated to preventive care.







• Public hospitals• Private hospitals• Rest homes• Foundations / charity institutionsWorking in those institutions:

- Physiotherapists- Osteopaths- Nurses

• Universities with healthcare education• Professional Healthcare Schools







• Fitness centre / gyms• Sanatorium = health Spa = convalescent home

• Individual clients:- End users (patients or clients)- Patients’ families

• Internet shops (for individual clients and institutions)• Shops / institutions which are specialized in selling /

renting rehabilitation equipment

• Insurance institutions

Business model Key processes How do we get the market?

• Promotion: different ways to promote energy harvesting to foot throttle can be done. Here we list the most important, considered in rehabilitation sector:

- Promotion to DMU (Decisions Making Units, like physiotherapists and other medical experts, insurance companies, hospitals, etc.)

Direct promotion (face to face) Incentive programs

- Promotion to end users Indirect promotion via DMU (personal and

non personal) Indirect promotion via e.g. health and life

style related fairs and magazines - Relationship building via

Professional guidance e.g. physiotherapists

User friendliness of software Regular software updates Rewarding programs for discipline etc.

Distribution channels: most of them are already existing (rehabilitation centers, hospitals, etc.)






Business model Key processes Business network

Customer Relationship Management (CRM) • Communication via

Physiotherapists: as they are the main link between rehabilitation devices and end usersHealth insurance companies: they can feed the organization with complementary performances of the productsMedia targeting elderly people and/or specific illness communities (for example: Associació Catalana de Diabètics): magazines, web sites, etc.

• Relationship building viaProfessional guidance by physiotherapists and other rehabilitation expertsUser friendliness of softwareRegular software updates

Rewarding programs for discipline and motivation (i.e. community games in a common area to permit social contact)






Business model Economic analysis

Calculation of ROI (Return Of Inversion): when doing the economic analysis of ROI, we are thinking in manufacturers companies, which already have existing manufacturing buildings and structure, and /or insurance companies, that should subcontract the engineering costs.• Estimated inversion for the project of device development: 700.000€

(that includes engineering costs, certifications, and manufacturing tools investment).

• Estimated inversion for marketing: 240.000€• Raw Materials: 350€ /unit• Selling price (considering 10% margin for manufacturing area plus 20% for

commercial margin): 455€• Sales forecast in Spain: considering that there is an estimated market of 3

million people on 2012, we expect the following sales:

ENERGY HARVESTING - MRHBusiness model Economic analysis




ENERGY HARVESTING

As a first economic approach we can conclude that on the 4th year of the project we would reach the break-even point. In this analysis we have to understand some considerations:

• Economic analysis has been done considering a manufacturer structure already existing, otherwise the costs would increase and break-even point would move to next years.

• Economic analysis has been done without considering any cofounding of the device: if there is a possibility of cofounding, the forecast sales would probably increase, so the break-even point can move to previous years.

• In the sales forecast there is an important commercial step between year 4 and year 5: if that becomes true, then it will be necessary to consider new manufacturing inversions, as probably the manufacturers is not provided with the needed infrastructure to give answer to this demand.
