Power Generation Properties and Bending Characteristics of a Flexible Thermoelectric Module Fabricated using PDMS Filling Method
正文
18쌍의 Bi2Te3계 p-n 가압소결체 열전레그들로 구성되어 있으며 상하부 기판이 없고 내부는 polydimethylsiloxane (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 \u0026#13244;의 최대출력전력이 얻어졌으며, 걸어가는 동적인 상태에서는 3.32 mV의 open circuit 전압과 3.41 \u0026#13244;의 최대출력전력이 얻어졌다. 유연열전모듈에 굽힘곡률반경 25 mm로 30,000회까지 반복굽힘 싸이클을 인가하여도 저항변화율이 1% 미만으로 유지되었다.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 \u0026#13244; 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 \u0026#13244; 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.

PDMS臻品推荐

PDMS-微流控基质材料-PDMS/道康宁SYLGARD184-聚二甲基硅氧烷/0.5KG(组)

产品说明书PDF自助在线看：http://www.pdmshub.com/sih

信息更新：

美国总工厂生产的0.5KG原始包装的PDMS延期至2021年9月16日后才能交货，默认我们将发国内库存的进口分装产品（02085925-0.5KG）；另受制于有机硅大幅涨价潮影响，2021年9月1日后将上调销售价格，另行通知。Dow Corning=道康宁=Dow SiL=陶氏，都是同一家公司。 2021.09.01更新

美国总工厂生产的0.5KG包装的PDMS恢复正常进口，合法正规，质量金标准，欢迎订购使用。并承诺从我司购买的皆为原厂包装,100%未开封,附带技术手册,非国产灌装仿制、非分装、非仿冒外包装产品,可以放心使用。大量订购更有优惠。2021.04.01更新

备注：由于dowsil与道康宁公司合并，美国总工厂生产的PDMS，价格涨幅高达1倍之多，因针对科研用户使用，特备货规格0.5KG。如果您需要美国总工厂原厂生产的大规格包装的预定，可以与QQ 11366508联系给予报价/货期。2021.05更新
