Something from nothing: Using waste heat to power electronics

Tsukuba, Japan (SPX) Feb 14, 2020

Collecting energy from environmental waste heat such as that lost from the human body is an attractive prospect to power small electronics sustainably. A thermocell is a type of energy-harvesting device that converts environmental heat into electricity through the thermal charging effect. Although thermocells are inexpensive and efficient, so far only low output voltages - just tens of mil
