Overview:Present system for ECG and EEGWhat is ELECTRONIC SKIN ?Advantages of it over present system.Applications.
Introduction: Electronics play a very important role in developing simple devices used for any purpose. The best achievement as well the future example of integrated electronics in the medical field is The Electronic skin.
The functioning of heart checked with the help of standard instruments which involves the concept of propagation of waves inside the body.
EEG systemIt is used forrecordingof electricalactivity alongthe scalp.
Electronic skin Ultra thinelectronic device.Attaches to theskin like a stick-ontattoo.Can measureelectrical activityof the heart ,brainwaves & othervital signs.
Idea : borrowed directly from kids’ temporary transfer tattoos. Attaches itself through weak forces of molecular attraction called Van de Waals interactions.Circuitry − "spider web" of materials: narrow snake-like silicon filaments that serve as wires connected to tiny sensors designed to monitor particular bodily functions.
Working: 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 skin to the receiver.
0ther Applications:Takes the signals of the body and transfer them to machines in other ways :- Muscle contractions in the neck can control the mouse in a computer game. Localized electrical stimulation; "smart bandage" : Temperature changes across a wound.
DEVELOPED BY: The scientists at the University of Illinois, Northwestern University in Illinois, Tufts University in Massachusetts, the Institute of High Performance Computing in Singapore and Dalian University of Technology in China.
ADVANTAGES: Reduces wires. Compact in size, less in weight. The device is so floppy, and flexible. DISADVANTAGES:Cost is highSingle use
Future Scope: In future even virtual screens may be placed on the device for knowing our body functions.
Conclusion: The Electronic devices gain more demand in the market when they are compact in size and best at functioning. The Electronic skin is one such device which depicts the beauty of electronics and its use in daily life.
