Thermoelectric Bracelet

hot-cold

I really need one of these. When the seasons change in Australia, since our houses generally lack much insulation or heating/cooling controls, sleeping can get annoying. Too hot when trying to fall asleep. Too cold half way through the night! Gah!

"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."
