Yang, YYYangZONG-HONG LINHou, TTHouZhang, FFZhangWang, ZLZLWang2023-03-202023-03-2020121998-0124https://scholars.lib.ntu.edu.tw/handle/123456789/629432We have developed a flexible thermoelectric nanogenerator (TENG) that is based on a Te-nanowire/poly(3-hexyl thiophene) (P3HT) polymer composite as the thermoelectric material with a positive Seebeck coefficient of 285 μV/K. A linear relationship between the output voltage of TENG and the temperature difference across the device was observed. Under a temperature difference of 55 K, two TENGs can provide an output voltage of 38 mV in serial connection, or a current density exceeding 32 nA/mm2 in parallel connection. We demonstrated that the flexible TENG can be used as a wearable energy harvester by using human body temperature as the energy source. In addition, the TENG can also be used as a self-powered temperature sensor with a response time of 17 s and a reset time of 9 s. The detection sensitivity of the sensor can reach 0. 15 K in ambient atmosphere. © 2012 Tsinghua University Press and Springer-Verlag Berlin Heidelberg.Te nanowires; Seebeck effect; thermoelectric nanogenerator; self-powered temperature sensor; POLYMER NANOCOMPOSITES; DEVICES; ENHANCEMENT; DRIVEN; ARRAYS; SYSTEMjournal article10.1007/s12274-012-0272-82-s2.0-84871337604WOS:000312406700006https://api.elsevier.com/content/abstract/scopus_id/84871337604
