This document discusses flexible e-skin technology, which can mimic human skin and measure vital signs like ECG and EEG readings. It has applications in robotics, medicine, and flexible electronics. The architecture of e-skin includes sensors, a wireless antenna, and power coil on an ultrathin film. It can be fabricated using materials like zinc oxide nanowires, gallium indium, and organic transistors and LEDs. E-skin is lightweight, compact, easy to attach and detach, and can replace current ECG and EEG systems. It has future applications in bendable displays, health monitoring, interactive surfaces, and smart devices.

9. zinc oxide with vertical
nanowires
 Based on
piezoelectricity and
electrical polarization
 Eight thousand
transistors
 Greater sensitivity and
resolution

10. Gallium Indium
 Multilayered embeded
microchannels
 Tactile sensing in
humanoid and
medical robotics
 channel dimensions-
200umx300um
 Sensor-25mmx25mm

11. Organic Transistors
 fabricated organic
transistors and tactile
sensors on an ultrathin
polymer sheet-1um thick
 withstand repeated
bending, crumple like
paper, and accommodate
stretching
 it works at high
temperatures and in
aqueous environments—
even in saline solutions

12. Organic Light Emitting
Diode
 Electronic skin respond
optically
 Array of pressure
sensing& Light emiting
pixels
 When the flexible skin is
touched, bent or
pressed, built-in LED’s
light up - and the
stronger the pressure,
the brighter the light

13. Application

 Light in weight
 It replaces present system of ECG and EEG
 Gives sense to a robot
 Wearable
 Ultrathin
 flexible ,Twistable & stretchable

14. Future Scope
 Bendable sensors and displays
 oncoming heart attack hours in advance.
 virtual screens may be placed on
device for knowing our body functions.
 car dashboard, interactive wallpapers,
smart watches.
