能量收集是从外部来源获得能量并将其转化为可用电能的过程。压电能量采集器的分析模型已经开发，以确定跨电路的输出电压时，它被迫进行基础激励。该模型为压电材料的设计和研究提供了一种简便的方法。已经进行了数值模拟，以确定的锆钛酸铅（PZT-5A）压电材料上的频率和负载的效果。已经观察到，当负载增加时，来自采集器的输出电压增加，而其谐振频率降低。分析结果与实验和数值模拟结果吻合较好。
Energy harvesting is the process of attaining energy from the external sources and transforming it into usable electrical energy. An analytical model of piezoelectric energy harvester has been developed to determine the output voltage across an electrical circuit when it is forced to undergo a base excitation. This model gives an easy approach to design and investigate the behavior of piezoelectric material. Numerical simulations have been carried out to determine the effect of frequency and loading on a Lead zirconate titanate (PZT-5A) piezoelectric material. It has been observed that the output voltage from the harvester increases when loading increases whereas its resonance frequency decreases. The analytical results were found to be in good agreement with the experimental and numerical simulation results.
