This document discusses the development of electronic skin (e-skin). It provides an overview and introduction to e-skin, which aims to mimic human skin. The objective is to develop flexible, compliant sensors. Key developments include attaching nanowire transistors to flexible substrates in 2010, creating stretchable solar cells to power e-skin in 2011, and developing a self-healing e-skin made of plastic and nickel in 2012. E-skin can measure vital signs, map pressure spatially, and be used in applications like robotics, health monitoring, and interactive devices. Future areas of development include using e-skin in vehicles and to predict medical issues in advance.

3. INTRODUCTION:
 Electronic plays a very important role in
developing simple devices used for any
purpose.
 It is a material which mimics the human skin
in one or more ways
 The best achievement as well as the future
example of integrated electronics in the
medical field is the electronic skin.

5. OBJECTIVE:
 Goal is to develop sensors on flexible
substrates that are complaint to curved
surfaces.
 Objective is for making an artificial skin is
to make a revolutionary change in robotics ,
in medical field , in flexible electronics.
 Main objective is to make sense whatever
which human sense.

6. DEVELOPMENT OF E-SKIN:
6
o 2010:
 Attaching a nanowire transistors to sticky
substrate , embedded in thin pressure
sensitive rubber –capable of sensing wide
range of pressures(California University)
 First prototype for e-skin
o 2011:
 Stretchable solar cell used to power the
electronic skin(Stanford)

7. 7
o 2012:
Self healing capacity
Made by plastic and nickel
o 2013:
Created an electronic skin that lights up when
touched (UC Berkeley)

8. E-SKIN FEATURES:
Optimization of pressure sensors and electronic
read out –but no human readable output..
The new e-skin :Spatially map the applied
pressure and instantaneous visual response
through OLED.
Can measure electrical activity of the heart ,
brainwaves & other vital signs.
It can record electrical activity along the scalp.

10. FABRICATION OF E-SKIN:
 By using zinc oxide with vertical nanowires
 By using Gallium Indium method
 By using Organic transistors
 By Organic Light Emitting Diode

11. ADVANTAGES:
 Reduces wires.
 Compact in size , less in weight.
 The device is so floppy , and flexible.
 It gives sense to a robot.

12. DISADVANTAGES:
• Cost is very high
• Single use
• Transpiration doesn’t take properly

13. APPLICATION
1. Automatic control panel
2. Interactive input devices
3. Robotics
4. Medical & Health monitoring device
5. Self-powering

15. FUTURE SCOPE:
• In future even virtual screens may be placed
on device for knowing our body functions.
• Used in car dashboard , interactive
wallpapers , smart watches , we can predict a
patient of an oncoming heart attack hours in
advance.

16. CONCLUSION:
 The electronics skin is one such device that
depicts the beauty of electronics and its uses
in daily life.
 The electronics devices gain more demand
in the market when they are in compact in
size and best in functioning.
