초록

18쌍의 Bi2Te3계 p-n 가압소결체 열전레그들로 구성되어 있으며 상하부 기판이 없고 내부는polydimethylsiloxane (PDMS)로 충진되어 있는 유연열전모듈을 형성하고, 이의 발전특성과 굽힘특성을 분석하였다. 유연열전모듈을 팔목에 부착하였을 때 서있는 정적인 상태에서는 2.23 mV의 open circuit 전압과 1.69 μW의 최대출력전력이 얻어졌으며, 걸어가는 동적인 상태에서는 3.32 mV의 open circuit 전압과 3.41 μW의 최대출력전력이 얻어졌다. 유연열전모듈에 굽힘곡률반경 25 mm로 30,000회까지 반복굽힘 싸이클을 인가하여도 저항변화율이 1% 미만으로 유지되었다.

Abstract

A flexible thermoelectric module, which consisted of 18 pairs of Bi2Te3-based hot-pressed p-n thermoelectric legs, were processed by filling the module inside with polydimethylsiloxane (PDMS) and removing the top and bottom substrates. Its power generation properties and bending characteristics were measured. With putting the flexible module on the wrist, an open circuit voltage of 2.23 mV and a maximum output power of 1.69 μW were generated during staying still. On the other hand, an open circuit voltage of 3.32 mV and a maximum output power of 3.41 μW were obtained with walking motion. The resistance variation of the module was kept below 1% even after applying 30,000 bending cycles with a bending curvature radius of 25 mm.
