IIT Students Innovate Vest That Keeps You Cool in Summers Warm in Winters #IndiaNEWS #Innovation
A month ago, when summer was at its peak in Mumbai, Rahul Bansal and Phalgun Vyas were attending the Invention Factory Programme 2022 at the IIT campus in the city.
The students of IIT Ropar and Madras respectively, Rahul and Phalgun were sharing a non-air conditioned hostel room at night and would rush to the comfortable AC hall during the day. This inspired their innovation at the event — a vest that keeps you cool during the summer and warm during winter.
The innovation grabbed the attention of jury members and received third prize in the event, which was attended by 20 selected students from IITs across the country. One jury member even showed interest in investing in their prototype, which has elated the innovators.
“The only mandate for the competition was that the invention should be something that solves current problems. We couldn’t think of a better option than something that will make our body feel comfortable during the extreme summer,�? shares Phalgun, a fourth-year dual degree student in BTech chemical engineering and MTech data science from IIT Madras.
The entire process of innovation — including pitching, patenting, and prototyping — was carried out during the six week event.
The first week was reserved for ideation and the remaining five for prototyping.
“We interacted with all the participants during the first week and I felt quickly connected to Phalgun’s ideas. Both of us are so prone to action and have complementary skill sets too. These brought us together and we turned into a team,�? recalls Rahul, a third-year mechanical engineering student from IIT Ropar.
Phalgun (20) says, “We felt it would be nice to feel comfortable in one’s clothes no matter what the temperature is outside, and even if one is commuting or sitting outdoors. This was the initial trigger to the thermoelectric cooling vest, in which we can set the preferred temperature manually. �?

The innovation includes a switch-enabled device which is placed inside a vest made of cotton and linen. This device uses thermoelectricity combined with a heat exchanger set up.
“When switched on, the vest begins providing either cooling or warmth, as per requirements. We consulted a cardiologist to carefully study body sensitivity so that we can cool or warm strategic parts of the body,�? Rahul explains.
He adds, “The batteries used are of low voltage and widely seen in wearables. Moreover, we provided appropriate circuitry to prevent short circuit, overcharging, and discharging of batteries. So the chances of electric shocks or explosions are restricted.
