A group of MIT graduates have created a bracelet that acts as a personal heating and cooling system.
The bracelet, called Wristify and developed by Cambridge-based Embr Labs, got its start last year at an annual MIT materials-science design contest that had one theme: sustainability.
The team brainstormed different ideas and settled on one big problem: buildings use so much energy.
“It’s really the people that need to be heated or cooled directly,” said Embr co-founder Sam Shames, a Newton native. The first prototype was born during the summer of 2013. Using thermoelectric technology, the bracelet can be used by a person to heat or cool themselves. There are two buttons, one for heating and one for cooling, and a slider that can be used to adjust the temperature of the bracelet.
Last October, the invention won the $10,000 first prize in that contest.
