ELECTRONIC SKIN
By Shaik Salman pasha 15N31A04L1
Electronic
skin is defined as set of multiple electronic and sensing components such as touch and temperature sensors , displays , energy scvengers and electronics Etc integrated on a flexible or bendable substrates.
E-Skin working principle
The core technology of the sensor material is a vast network of semiconductor nanowires.
Change in material thickness is electrically measured through transistors and capacitors.
Temperature sensors are used for measuring the temperature
Strain gauges are used for measuring the signals generated by the heart.
Antenna is used for transmitting the recorded signals of the skin to the receiver.
Printing of active/passive Electronic and sensing components.
In this case sensors are directly printed on flexible substrate. Integration of graphene into skin like electronic device find applications ranging from new generation temp/pressure sensors.
APPLICATIONS
The E-Skin Sensors Can Be Fixed to the Skin Like Temporary Tattoos
Health monitoring(EEG,ECG)
In the field of robotics.
TRADITIONAL APPROACH
ADVANTAGES
Reduses wires
Compact in size , less in weight
The device is flexible
DISADVANTAGES
Cost is high
Single use
FUTURE SCOPE
In future even virtual screens may be placed on the device to know our body functions.
