Abstract Experiments to determine the effects of mechanical fastener induced pre-stress on a piezoelectric energy harvester (PEH) were conducted. Using a mechanical pre-stress fixture and an electro-dynamic MTS material tester, experiments conducted on soft-PZT showed that are optimized PEH by modulating the magnitude of pre-stress induced on the soft-PZT. Experiments also showed that by adjusting the number of mechanical fasteners used to induce the pre-stress, the energy harvesting capabilities of a PEH may be further optimized.

机械紧固件诱导预应力对软 PZT 能量收集器功率效率的影响

摘要 进行了确定机械紧固件引起的预应力对压电能量收集器 (PEH) 的影响的实验。使用机械预应力夹具和电动 MTS 材料测试仪，在软 PZT 上进行的实验表明，通过调节软 PZT 上感应的预应力大小来优化 PEH。实验还表明，通过调整用于诱导预应力的机械紧固件的数量，可以进一步优化 PEH 的能量收集能力。
