Flexible Device Harvests More Body Heat

Sep-13-16 A new device able to harness electricity from body heat has proven to be much more efficient than current heat harvesting devices.

Developed by a team from North Carolina State University, the prototype device is made without a heat sink, which allows it to be lightweight and more comfortable. The thermally conductive layer of the device sits on the skin to capture the heat, while a polymer layer on top keeps the heat from escaping and directs it to a small, onboard TEG for conversion into electrical energy. The entire device is only two millimeters thick, but can generate up to twenty microwatts of power per square centimeter.
