Wristwatch Can Alter Body Temperature

For those that are always cold, this is a perfect invention.


wristify-watch-gadgetDesigners have developed a thermoelectric ‘watch’ which can alter human body temperature – drastically slashing air conditioning and heating costs.

The gadget, called Wristify, has the ability to change a person’s temperature by several degrees and can work at a rate of 0.4 degrees a second.

Students at the Massachusetts Institute of Technology found a 0.1 degree a second change in temperature of one part of the body makes the entire body feel several degrees warmer or cooler.

This would then help to save on energy bills as increasing the temperature of a large building by one degree can use up around 100kWh a month.

Wristify is still a prototype but it uses a copper-alloy-based heat sink on the wrist and is able to automatically measure your body temperature and then make adjustments to maintain the level you set it at.

The bracelet has a lithium polymer battery inside and is able to work for eight hours.
Sam Shames, who co-invented the Wristify alongside Mike Gibson, David Cohen-Tanugi and Matt Smith, said: “Buildings right now use an incredible amount of energy just in space heating and cooling.

“In fact, all together this makes up 16.5 per cent of all US primary energy consumption.

“We wanted to reduce that number, while maintaining individual thermal comfort. We found the best way to do it was local heating and cooling of parts of the body.”

The team recently came first in the MIT Making and Design Materials Engineering Competition and won $10,000 (£6200) which they are going to reinvest into the Wristify project.
