摘　　要：热电发电器是固态能量收集器,以可靠和可再生的方式将热能转换成电能。过去几年的研究表明,人体的热量可以很好地被柔性热电发电器转换为电能并加以利用。与用于可穿戴设备的其他传统发电器相比,柔性热电发电器可利用低品位的热能发电且环境友好。柔性热电发电器将有可能为任何无线传感器节点提供足够的能量(通常功率要求小于毫瓦级)。本文综述了热电发电器的概况,重点介绍了制造柔性热电发电器的关键工艺,讨论了热电发电器的基本原理、效率、应用以及存在的一些问题。Thermoelectric generators are solid state energy collectors which can convert thermal energy into electrical energy in a reliable and renewable manner.In the past few years,it has been considered that the heat of human body could be effectively converted to electrical energy by flexible thermoelectric generators.Moreover,flexible thermoelectric generators are able to use low-grade thermal energy to generate electricity and they are environmental friendly compared to other conventional generators applied in many wearable devices.Besides,it is worth mentioning that flexible thermoelectric generator is potential to generate sufficient energy for any wireless sensor nodes(usually the power requirements is less than milliwatt).In this article,the general research situation of thermoelectric generators is reviewed,and several key techniques for flexible thermoelectric generator manufacturing are introduced with emphasis.The basic principle,efficiency,applications and existing problems of thermoelectric power generator are also discussed.
