Abstract

In this study, a novel piezoelectric energy harvester (PEH) based on the array composite spherical particle chain was constructed and explored in detail through simulation and experimental verification. The power test of the PEH based on array composite particle chains in the self-powered system was realized. Firstly, the model of PEH based on the composite spherical particle chain was constructed to theoretically realize the collection, transformation, and storage of impact energy, and the advantages of a composite particle chain in the field of piezoelectric energy harvesting were verified. Secondly, an experimental system was established to test the performance of the PEH, including the stability of the system under a continuous impact load, the power adjustment under different resistances, and the influence of the number of particle chains on the energy harvesting efficiency. Finally, a self-powered supply system was established with the PEH composed of three composite particle chains to realize the power supply of the microelectronic components. This paper presents a method of collecting impact energy based on particle chain structure, and lays an experimental foundation for the application of a composite particle chain in the field of piezoelectric energy harvesting.

摘要

在本研究中，构建了一种基于阵列复合球形粒子链的新型压电能量收集器（PEH），并通过模拟和实验验证对其进行了详细探究。实现了基于阵列复合粒子链的PEH在自供电系统中的功率测试。首先，构建了基于复合球形粒子链的PEH模型，从理论上实现冲击能量的收集、转换和存储，验证了复合粒子链在压电能量收集领域的优势。其次，建立了实验系统来测试PEH的性能，包括连续冲击载荷下系统的稳定性、不同电阻下的功率调节以及粒子链数量对能量收集效率的影响。最后，用由三条复合粒子链组成的PEH建立了自供电系统，以实现对微电子元件的供电。本文提出了一种基于粒子链结构收集冲击能量的方法，为复合粒子链在压电能量收集领域的应用奠定了实验基础。
