An MP3 player comes in the form of a band aid that sticks on your arm and it’s powered by your body heat. This is definitely what we’ve been looking for, a device that continuously runs for many hours for music without hassles of having to recharge its battery.
The body heat-powered MP3 player is currently just a concept by Chih-Wei Wang and Shou-Hsi Fu. The device comes with everything simple, it just has a simple button for turning on and off and embedded speakers for blasting music. It should be able to work with your headphones via Bluetooth to free you from tangles of wires. And the best is it doesn’t require batteries!
