Body Heat Harvest

North Carolina State University researchers have developed garments that harvest body heat and turn it into electricity. The shirt prototypes can generate more electricity than previous heat harvesting technologies. So called TEG's ( Thermo Electric Generators) work by harnessing the temperature difference between the wearer's skin and the air around them. The paper, “Wearable thermoelectric generators for human body heat harvesting,” is published in the journal Applied Energy.
