Wearable solar thermoelectric generator created A recent study, led by Professor Kyoung Jin Choi in the School of Materials Science and Engineering at UNIST has introduced a new advanced energy harvesting system, capable of generating electricity by simply being attached to clothes, windows, and outer walls of a building. This new device is based on a temperature difference between the hot and cold sides. The temperature difference can be increased as high as 20.9 °C, which is much higher than the typical temperature differences of 1.5 to 4.1 °C of wearable thermoelectric generators driven by body heat. The research team expects that their wearable solar thermoelectric generator proposes a promising way to further improve the efficiency by raising the temperature difference. Energy harvesting is a diverse field encompassing many technologies, which involve a process that captures small amounts of energy that would otherwise be lost as heat, light, sound, vibration, or m...
