Wearable solar thermoelectric generator
Professor Kyoung Jin Choi at UNIST has introduced a new advanced energy harvest system, capable of generating electricity by being attached to clothes, and windows. The thermoelectrical generator is based driven by body heat. This device's goal is to improve efficiency by raising the temperature difference. One of the main drawbacks of the technology is body heat that such temperature difference is only 1--4 degrees Celsius. However the team solved this issue by introducing a local solar absorbed on a P1 substrate.
Professor Choi integrated flexible BiTe-based TE legs and sub micron thick solar absorbers on polymide substrate."Our new wearable STEG is expected to be useful in various applications, such as in self-powered wearable electronic devices," says Professor Choi. Professor believes that his technology will create plenty of talk and be a hot buy no pun intended.
