This document discusses electronic skin (e-skin), which is a thin, flexible material designed to mimic properties of human skin like sensitivity to pressure and temperature. It provides an overview of e-skin, including its development over time from 2010 to 2013, features like sensing pressure and vital signs, structure with sensors and displays, applications in devices, and future potential uses in areas like healthcare monitoring. The conclusion notes that e-skin allows for more compact and functional electronic devices that emulate human touch.

3. What is electronic skin ?
A thin layer of material containing electronic
sensors that is designed to mimic some of the
properties of human skin, especially its sensitivity to
pressure and temperature.
INTRODUCTION:

4. DEVELOPMENTOF E-SKIN:
• 2010:
Attaching 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
• 2011:
Stretchable solar cell used to power the electronic skin(Stanford)
• 2012:
Self healing capacity
Made by plastic and nickel
• 2013
Created an electronic skin that lights up when touched (UC Berkeley)

5. E-SKINFEATURES:
• Optimization of pressure sensors &
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.
• Muscle contractions in the neck can
control the mouse in a computer

6. STRUCTUREOF PIXELOF E-SKIN:
• Nanotube TFT drain connected to
anode of OLED.
• OLED: Bi-layer structure whose
color controlled by emissive layer
material.
• PSR: Electrical contact with cathode
of OLED.
• Conductivity of PSR α applied
pressure.

7. HOWTOCONVERTDISPLAYINTOE-SKIN:
• PSR lamination on the top of the leads to make Pressure
sensitive.
• The cathode of each OLED is connected to the ground through
PSR. Application of pressure: shortening of tunneling path
between conductive carbon nano particles-reduced resistance
of PSR modulates the current flowing through the OLEDs and
changes the brightness of the output.

8. VIDEODEMONSTRATIONOF E-SKIN

9. ADVANTAGES:
• Reduces wires.
• Compact in size, less in weight.
• The device is so floppy, and flexible.

10. APPLICATIONS:
• Automatic control panel
• Interactive input devices
• Robotics
• Medical & Health monitoring device

11. FUTURESCOPE:
o IN FUTURE EVEN VIRTUAL SCREENS MAY BE PLACED ON DEVICE FOR KNOWING
OUR BODY FUNCTIONS.
o USED IN CAR DASHBOARD, INTERACTIVE WALLPAPERS, SMART WATCHES. WE CAN
PREDICT A PATIENT OF AN ONCOMING HEART ATTACK HOURS IN ADVANCE.

12. CONCLUSION:
THE ELECTRONICS DEVICES GAIN MORE DEMAND WHEN THEY ARE
COMPACT IN SIZE AND BEST AT FUNCTIONING. THE ARTIFICIAL SKIN IS ONE
SUCH DEVICE WHICH DEPICTS THE BEAUTY OF ELECTRONICS AND ITS USE IN
DAILY LIFE. SCIENTISTS CREATE ARTIFICIAL SKIN THAT EMULATES HUMAN
TOUCH. ACCORDING TO EXPERTS, THE ARTIFICIAL SKIN IS "SMARTER AND
SIMILAR TO HUMAN SKIN."
