摘要

提出了利用气动高压激励的阵列式盘型压电俘能器实现气体能量的转化，以满足低功耗传感器的自供能需求。通过压电单晶片将气缸内部高压气体能量转化为电能，设计了阵列式盘型压电俘能器的样机结构；结合气缸的正常工作状态，分析了压电阵列的工作原理并进行了相应的实验。理论分析显示：盘型压电阵列具有较高的电荷量与良好的电容性，适合对具有交变载荷的高压气体能量进行收集。采用外径为12 mm、厚度为0.2 mm的压电单晶片及缸径为63 mm、行程为150 mm的气缸制作了实验样机，利用气动组件模拟气体环境搭建了测试系统。分别调节压力、周期、流量等参数进行了实验测试。结果表明：在交变的气动高压激励下，阵列式盘型压电俘能器可较好地收集交变高压气体载荷能量，其最佳匹配电阻为600 kΩ，最大的瞬时功率为1 052

W，输出功率可满足低功耗传感器的能量需求。

Abstract

An array piezoelectric plate harvester excited by pneumatic compressed air was proposed to implement gas energy conversion and to satisfy the demand of energy supplying for low-power wireless sensors. By converting the alternate high air pressure energy in a pneumatic system into the electric energy with piezoelectric plates

the structure of a prototype for the array piezoelectric plate harvester system was designed. Then

based on the normal working states of the presented harvester

its working principles were introduced and corresponding experiments were performed. The theoretical analysis results show that the array piezoelectric plate has high output voltage capacities and collects the compressed gas energy effectively. An experimental prototype was fabricated by combing a piezoelectric single chip with a diameter of 12 mm and a thickness of 0.2 mm and an air cylinder with a diameter of 63 mm and a travel of 150 mm. A test system was built to research the performance of array piezoelectric plate harvester in simulated gas conditions. In the test

the pressures

cycles and flows were adjusted

respectively. Experimental results at the alternate high air excitation show that the proposed harvester collects the load gas energy of alternate high pressure air

and its optimal load resistance is 600 kΩ and instantaneous power is 1 052

which meets the demands of low power sensors for energy applying.
