IIT-Kharagpur researchers awarded for producing energy from moist garments

Kolkata, August 3

A bunch of researchers from IIT Kharagpur has been conferred the ‘Gandhian Young Technological  Innovation Awards 2020’ for creating a mechanism for producing electrical energy from moist garments left beneath daylight to dry, a spokesperson of the institute stated on Monday.

Another workforce from the institute was individually granted the identical award for addressing the issue of power conservation and thermal administration in wearable and versatile digital units.

Congratulating the researchers, IIT Kharagpur Director Prof Virendra Tewari stated: “We still have sectors which need sourcing and efficient management of clean energy to meet our augmented power requirements, even in the remote areas”.

The ‘Gandhian Young Technological Innovation (GYTI) Awards’ was instituted by the Society for Research and Initiatives for Sustainable Technologies and Institution (SRISTI), a voluntary group.

SRISTI stated that GYTI Award celebrates the spirit of pupil innovation in all of the fields of engineering, science, expertise and design by way of extraordinarily inexpensive/frugal answer or those pushing the technological edge.

The spokesperson stated that Prof Suman Chakraborty, Prof Partha Saha and Dr Aditya Bandopadhyay from the Department of Mechanical Engineering have been awarded for his or her work – “Electrical power generation from wet textile”.

Prof Sunando Dasgupta and his workforce from the Department of Chemical Engineering have additionally been awarded for his or her work— ‘Smart, flexible, and multi-functional thermal and energy management systems for next-generation electronic devices’.

The novelty of the primary innovation, the nano- electrical energy generator, is in its frugal means as a substitute of power harvesting from advanced sources, the spokesperson stated.

The machine has been examined in a distant village the place round 50 moist garments have been left for drying by washermen. These garments have been related to a business supercapacitor which discharged electrical energy of round 10 volt. This saved power is sufficient to glow a white LED bulb for greater than an hour.

“The clothes we wear are made from cellulose-based textile which has a network of nano-channels. Ions in saline water can move through this interlace fibrous nano-scale network by capillary action inducing an electric potential in the process,” defined the researchers from the division of mechanical engineering.

The work has been revealed in Nano Letters, a high-impact journal within the area, and the innovation has been patented by them.

The group led by Prof Sunando Dasgupta has been working in collaboration with Purdue University, USA, to handle the issue of power conservation and thermal administration in wearable and versatile digital units, the spokesperson stated.

They achieved this by leveraging the distinctive properties of ‘smart materials’  supplies that sense and react to environmental situations or stimuli reminiscent of mechanical, chemical, electrical, or magnetic alerts infused with graphene, a type of carbon. PTI
