• Nanotech dermal display is a designer concept, based on real nanoscienceprinciples.
• Seattle-based designer Gina Miller, working together with nanotech populariser
Robert A. Freitas Jr., describes the concept.
• It’s a programmable dermal display” in which a population of about 3 billion
display pixel robots would be permanently implanted a fraction of a mm under thesurface of the skin, covering a rectangle 6 cm x 5 cm on the back of the hand.
• Photons emitted by these pixel bots would produce an image on the surface of the
skin. This pixelbot array could be programmed to form any of many thousands of
displays.
• Each display would be capable of two functions:
– (1) presenting to the user data received from the large population of medical bots that
roam the user’s body;
– (2) conveying instructions from the user to that same large population of bots. The
display could be activated or deactivated by finger tapping on the skin.

• Nanorobots are nanodevices that will be
used for the purpose of maintaining andprotecting the human body againstpathogens.
• They will have a diameter of about 0.5 to 3microns and will be constructed out of partswith dimensions in the range of 1 to 100
nanometers.• The main element used will be carbon in
the form of diamond / fullerenenanocomposites because of the strengthand chemical inertness of these forms.
• Many other light elements such as oxygenand nitrogen can be used for specialpurposes.
• Such devices have been designed in recentyears but no working model has been builtso far.

• The powering of the nanorobots can be done bymetabolising local glucose and oxygen for energy.
• Communication with the device can be achievedby broadcast-type acoustic signalling.
•
A navigational network may be installed in the body, withstationkeeping navigational elements providing highpositional accuracy to all passing nanorobots thatinterrogate them, wanting to know their location.
• This will enable the physician to keep track of the various
devices in the body.• These nanorobots will be able to distinguish between
different cell types by checking their surface antigens (theyare different for each type of cell).

• Consider a population of ~3 billion display nanorobots embedded 200-300microns below the surface of the epidermis covering a 6 cm x 5 cmrectangle on the flat part of the back of the hand or on the smooth medialsurface of the forearm.
• The nanorobots are ~1 micron3 in volume and occupy only 1% of the 300mm3 local tissue deployment volume. Each device consumes ~10 pW
when generating visible photons of desired colors at a comfortable visibleintensity of ~1 pW/micron2 or ~1 watt/m2 , assuming an improved 10%ergooptical conversion efficiency.
• Visible photons are completely scattered in 10-100 microns but almostnone are absorbed, producing a diffuse glow as ~50% of the scatteredphotons eventually exit the surface of the skin.
• For installation and stationkeeping, display nanodevices require at leastlimited mobility, and a few additional nanodevices may be required toassist with computation, data storage and external communications, andother housekeeping chores.

• If powered by continuously available chemical fuels, the displaywould only be operable for 0.1-10 sec before exhausting the entireoxyglucose supply present in the limited tissue deployment volume.
• Consequently, it is necessary to include a large energy storagebuffer constituting 40% of device volume, which allows ~1000 sec
of operation if only 20% of all pixels are radiating at any given time.• This power can be reabsorbed from local oxyglucose supplies in ~1
day, giving a long-term ~1% duty cycle for the display (~14 min/day)although the buffer can operate the display for up to ~21 minutesbefore being exhausted.
• This power restriction may be entirely avoided by addingsupplemental power from, say, a wristwatch-sized extradermalacoustic source, a dedicated transvascular energy organ,photoelectric, or by employing a passive (reflective) display whichmight be satisfactory for some purposes.

• The array of 3 billion nanorobots may be programmed to adopt
any of many thousands of different displays . Each display
configuration is capable of
–
1. presenting output data received from the larger in vivo nanorobotpopulation scattered throughout the body (via a communication
network), and
– 2. accepting input data from the patient to be conveyed (through the
communication network) to appropriate internal nanorobot
subpopulations.

• The Dermal Nanotech display can be used for
monitoring body metabolism.
• Patients can keep track of their blood
pressure, sugar level, and heart rate to avoid
unwanted adversity .
• Full-motion animation or video may also be
projected, up to the 107 bit/sec maximum
limit of the mobile communication network.

• It is innovative technology in field of medical
science and Nano robotics.
• No need of huge external power source, it
uses oxyglucose for energy source or a simple
wrist watch like device for energy.
• It only requires one time installation, and lasts
forever.
• One can use own body as a display device.

• Expensive.
• The display may be partly obscured by
excessive body hair or particularly dark dermal
pigmentation.
• Post-installation bruises, scabs, incisions,
scars, or even wrinkling on the back of the
hand may slightly or temporarily impair
readability.

• future medical nanotechnology is expected to
employ nanorobots injected into the patient
to perform work at a cellular level. Such
nanorobots intended for use in medicine
should be non-replicating, as replication
would needlessly increase device complexity,
reduce reliability, and interfere with themedical mission.
