WEARABLE SUPERCAPACITOR

May 19, 2019

Researchers at the Indian Institute of Technology (IIT) Bombay have fabricated a wearable supercapacitor that can store and deliver large amount of electrical energy, exceeding other similar devices.

About:

Features: The wearable energy storage device can be stitched on to any fabric. It can deliver power ranging from microwatt to milliwatt.
Mechanism:
- The idea is when the supercapacitor is integrated with a piezoelectric energy generator then it will become completely self-sustaining.
- The electrode of the supercapacitor was fabricated by uniformly coating cotton yarn with carbon nanotubes (CNTs). The coating converts the electrical insulating yarn into a metallic conductor thereby behaving like an electrode.
Application: The energy stored in the device can power GPS location-based transmitters or a 1.8 volt LED. When stitched to the fabric, the supercapacitor can be used for powering GPS location based devices or a LED lamp or even charge small electronic devices.
