利用热电（TE）效应获取热能是体域网电源的潜在方法之一。本文提出了一种新的方法，电化学沉积过程中制造的自耐力柔性热电发电机（FTEGs）。提出了一种新的想法，横向Y型TE电池，而不是传统的垂直it π型电池，以提高温度采集的性能。另一方面，成功地合成了热电材料（N型碲化铋和P型碲化锑）厚膜。热电材料的电化学沉积首次用于将热电材料与柔性支撑件集成，其中硅衬底用作牺牲材料。利用人体（约37摄氏度）和周围环境（15摄氏度）之间的温差，利用自然对流，该装置可以产生约3 μ W/cm（2）的输出功率密度。(C)2017爱思唯尔有限公司版权所有
The harvest of thermal energy using the thermoelectric (TE) effect is one of the potential methods for body area network power sources. This paper demonstrates a new approach of an electrochemical deposition process to fabricate self-endurance flexible thermoelectric generators (FTEGs). A novel idea of lateral Y-type TE cells instead of conventional vertical it pi-type cells is proposed to enhance the performance of the temperature harvest. On the other hand, the thick films of thermoelectric materials (N type bismuth telluride and P type- antimony telluride) are successfully synthesized. For the first time, the electrochemical deposition of thermoelectric materials is used to integrate thermoelectric materials with a flexible support, where a silicon substrate is used as a sacrificial material. With the temperature difference between the human body (approximately 37 degrees C) and ambient environment (15 degrees C) using natural convection, the device can generate approximately 3 mu W/cm(2) of output power density.
