MIT prize winning invention regulates body temperature

Sometimes you’re too hot. Other times you’re too cold. This little device is designed to make you just right all the time.

Heating or cooling certain parts of your body — such as applying a warm towel to your forehead if you feel chilly — can help maintain your perceived thermal comfort.

Using that concept, four MIT engineering students developed a thermoelectric bracelet that monitors air and skin temperature, and sends tailored pulses of hot or cold waveforms to the wrist to help maintain thermal comfort.
