3. Electronics plays a very important role in developing simple
devices used for any purpose.
In every field electronic equipment's are required.
The best achievement as well as future example of integrated
electronics in medical field is Artificial Skin.
It is ultrathin electronics device attaches to the skin like a sick
on tattoo which can measure electrical activity of heart, brain
waves & other vital signals.
INTRODUCTION
4. ELECTRONIC SKIN
It made from biocompatible
silicon rubber with pressure
sensitive sensors.
It can measure electrical
activity of the heart, brain
waves and other vital signs.
Ultra-thin skin turn on hand
e-skin can be directly
laminated on the surface of the
skin, allowing us to
electronically functionalize
human skin.
It attaches to the skin like a
stick-on tattoo.
5. DEVELOPMENT OF E-SKIN
2010:
a) attaching nanowire transistor to sticky substrate, embedded
in thin pressure sensitive rubber capable of sensing wide range
of pressure (California university)
b) First prototype for e-skin
2011:
a) stretchable solar cell used to power the electronic skin
(Stanford).
2012:
a) self-healing capacity b) Made by nickel and plastic

7. FABRICATION OF E-SKIN
U.S. and Chinese Scientists used zinc oxide vertical nanowires
to generate sensitivity. According to experts, the artificial skin
is "smarter and similar to human skin.
To achieve this sensitivity, researchers created a sort of
flexible and transparent electronics sheet of about eight
thousand transistors using vertical nanowires of zinc oxide.
Each transistor can directly convert mechanical motion and
touch into signals that are controlled electronically
8. WORKING
Antenna is used to transmit the recorded electrical signals of
skin to the receiver.
Strain gauges are used for measuring the signals generated
by the heart.
Temperature sensors are used for measuring the temperature.
Electronic skin refers to flexible, stretchable and self-healing
electronics that are able to mimic functionalities of human or
animal skin.

10. By Organic Light
Emitting Diode
The researchers combined a
conductive, pressure-sensitive
rubber material, organic light
emitting diodes (OLEDs), and
thin-film transistors made of
semiconductor-enriched carbon
nanotubes to build an array of
pressure sensing, light-emitting
pixels. Whereas a system with
this kind of function is relatively
simple to fabricate on a silicon
surface, ―for plastics, this is
one of the more complex
systems that has ever been
demonstrated
11. APPLICATIONS
It takes the signals from the body and transfer
them to the device.
Localized electrical stimulation: “smart bandage”
temperature changes across the wound.
Muscle contractions in the neck can control the
mouse in computer game.
12. ADVANTAGES
Stretchable sensor system able to measure pressure.
Strain composed of buckled CNT-based electrodes.
The right-most pane depicts the pressure distribution
measured by pressing on the center pixel.
Recent devices have already surpassed the capabilities of
biological skin in terms of sensitivity, spatial resolution, and
stretchability.
DISADVANTAGES
Cost is very high.
Single use.
14. FUTURE SCOPE
In future even virtual screens may be placed on the device for
knowing our body function.
It has bright future in robotics industries to make it sensible
also.
In future even virtual screens may be placed on device
for knowing our body functions. Used in car dashboard,
interactive wallpapers, smart watches.
Artificial skin is "smarter and similar to human skin."
15. CONCLUSION
The electronics skin is one such device that depicts the beauty
of electronics and its uses in daily life.
The electronic devices gain more demand in the market when
they are in compact in size and best in functioning.
