IIT Kharagpur Researchers Awarded For Producing Energy From Moist Garments
A gaggle of researchers from IIT Kharagpur has been conferred with the ‘Gandhian Younger 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 mentioned on Monday. One other 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 mentioned: “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 research works awarded have etched their mark in both frugal innovation and those expanding the technological edge in the area of energy management with direct community impact,” he mentioned.
The ‘Gandhian Younger Technological Innovation (GYTI) Awards’ was instituted by the Society for Analysis and Initiatives for Sustainable Applied sciences and Establishment (SRISTI), a voluntary group. SRISTI mentioned 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 or frugal resolution or those pushing the technological edge.
The spokesperson mentioned that Prof Suman Chakraborty, Prof Partha Saha and Dr Aditya Bandopadhyay from the Division 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 Division 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 assets, the spokesperson mentioned. The machine has been examined in a distant village the place round 50 moist garments had been left for drying by washermen. These garments had been related to a industrial super-capacitor 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 College, USA, to deal with the issue of power conservation and thermal administration in wearable and versatile digital units, the spokesperson mentioned. They achieved this by leveraging the distinctive properties of ‘good supplies’ supplies that sense and react to environmental circumstances or stimuli akin to mechanical, chemical, electrical, or magnetic indicators – infused with graphene, a type of carbon.
“The material harvests the biomechanical energy of the user while storing the same and converting it into thermal energy towards the power management of the devices,” Dasgupta mentioned.
