Scientists at IIT Kharagpur Use Waste Onion Skins to Develop Green Electricity!
India Times (December 19, 2017)
Inventing yet another source of green electricity to protect the environment, scientists at IIT Kharagpur have used waste onion skins to develop an inexpensive device that can generate green electricity from body movements, and may power pacemakers, smart pills and wearable electronics.
The non-toxic, biodegradable and biocompatible device takes advantage of the suitable piezoelectric properties of the onion skin, researchers said.
Piezoelectic materials have the ability to convert energy from everyday mechanical motions into electricity.
"This homespun inexpensive innovative finding can be a breakthrough scientific research in a new direction; even common people can generate energy in any circumstances using this simple novel cost-effective idea," Bhanu Bhusan Khatua, professor at the Indian Institute of Technology (IIT) Kharagpur in West Bengal, told PTI.
