ABSTRACT The field of waste thermal energy harvesting has experienced significant growth over the past few years. This paper presents an experimental study on thermal radiation to electrical energy conversion using pyroelectric material (PbZrxTi1-xO3 (PZT-5H)). Pyroelectric material was exposed to UV lamp with a constant frequency of 0.5 Hz and another surface of sample was continuously cooled via natural air fan (for generation continuous temporal gradient in material). Maximum value of stored energy was 1.75 µJ across 100 µF without load resistance. Maximum power output was found to be 0.76 µW across load resistance of 3 MΩ and 10 µF.

使用热释电材料 (PZT-5H) 收集热能（通过辐射）：一项实验研究

摘要 在过去几年中，废热能收集领域经历了显着增长。本文介绍了使用热释电材料 (PbZrxTi1-xO3 (PZT-5H)) 将热辐射转化为电能的实验研究。热释电材料暴露在恒定频率为 0.5 Hz 的紫外灯下，样品的另一个表面通过自然风扇连续冷却（用于在材料中产生连续的时间梯度）。在没有负载电阻的情况下，在 100 µF 范围内存储的能量最大值为 1.75 µJ。发现在 3 MΩ 和 10 µF 的负载电阻上的最大功率输出为 0.76 µW。
