Researchers at Massachusetts Institute of Technology (MIT) have come up with a new gadget that can significantly cut the amount of energy required to create comfortable temperatures during extreme climates.
Known as Wristify, the device is a thermoelectric bracelet that measures the temperature of the surrounding environment and the skin temperature and sends pulses of hot or cold waves to the wrist which in turn changes the temperature of the entire body.
The bracelet is powered by a lithium polymer battery which can run without requiring a charge for eight hours.
"Buildings right now use an incredible amount of energy just in space heating and cooling. In fact, all together this makes up 16.5 percent 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", Sam Shames, who worked on the project, said.
