MIT Students Develop Wearable Cooling Device That Could Make Air Conditioning Obsolete




” We come across quite a lot of cool technology, but it’s not every day that we find something that can literally cool you down. 

Developed by four engineering students at MIT, Wristify is a prototype wearable device that leverages the physical phenomenon known as the Peltier effect to reduce your body temperature.

Wristify is basically a series of these junctions (called a Peltier cooler) powered by a small battery and attached to a wrist strap. When placed against the skin, the device makes you feel cooler by reducing the temperature of your wrist a few fractions of a degree per second for a couple seconds at a time. Over the course of a few minutes, this process will cause you to perceive a whole-body cooling of a couple degrees Celsius. “
