虽然电化学沉积热电材料是一种潜在的应用方法，如柔性热电发电机(FTEGs)，但到目前为止，该技术的应用有限。本文介绍了一种利用电化学法沉积热电材料制备自支撑pi型FTEGs的新方法。基于Bi2Te_3-Cu和Bi2Te_3-Sb_2Te_3两种类型的器件已经完全完成并进行了表征。Bi2Te3-Cu和Bi2Te3-Sb2Te3器件由24对热电偶组成，可以从与人体相差约2摄氏度-4摄氏度的温差中获取热能，输出功率密度为1-4微瓦厘米(-2)。这项工作展示了高度可扩展的新器件，为电化学沉积热电材料的应用开辟了机会。
Although the electrochemical deposition of thermoelectric materials is a potential method for applications such as flexible thermoelectric power generators (FTEGs), to date the use of this technique is limited. This paper demonstrates a new fabrication of self-supported pi-type FTEGs using electrochemical deposition of thermoelectric materials. Two types of the devices based on Bi2Te3-Cu and Bi2Te3-Sb2Te3 have been fully completed and characterized. The Bi2Te3-Cu and Bi2Te3-Sb2Te3 devices consist of 24 pairs of thermocouples that can harvest thermal energy with output power densities of 1-4 mu W cm(-2) from temperature differences of approximately 2 degrees C-4 degrees C from the human body. The highly scalable and new devices demonstrated in this work open up opportunities for the applications of electrochemically deposited thermoelectric materials.
