摘要

柔性热电能量收集器（f-TEHs）可将可穿戴传感器或电子设备连接到带有热源的曲面物体上。我们展示了一种堆叠结构的 f-TEH，它能在不增加横截面积的情况下产生热能。该器件由 p 型和 n 型 Bi2Te3 与聚（偏氟乙烯）、铝箔和聚对苯二甲酸乙二醇酯薄膜制成的热电复合膜组成。输出性能随着热电薄膜层数（L）的增加而提高，L = 8 f-TEH 可产生最大电压、电流和功率。研究采用了多物理场仿真和弯曲试验进行进一步研究。这项研究展示了一种独特的配置，并理解了其能量产生机制。

Flexible Thermoelectric Energy Harvester with Stacked Structure of Thermoelectric Composite Films Made of PVDF and Bi2Te3-Based Particles

Flexible thermoelectric energy harvesters (f-TEHs) enable wearable sensors or electronic devices to be attached on curved objects with a thermal source. We demonstrated a stacked-structured f-TEH that generates thermal energy without increasing its cross-sectional area. The device consists of thermoelectric composite films fabricated by p- and n-type Bi₂Te₃ and poly(vinylidene fluoride), Al foil and polyethylene terephthalate film. The output performance improved as the number of thermoelectric film layers (L) increased, and the L = 8 f-TEH generated maximum voltage, current, and power. Multiphysics simulations and bending tests were adopted for further investigation. This study demonstrates a distinctive configuration and comprehension of its energy generation mechanism.
