Experiment on Piezoelectric Plate Array Energy Harvester Excited by Alternate High Air Pressure with Constantly Gaseous Mass
摘要
Abstract
A piezoelectric plate array energy harvester was proposed,which was excited by constant mass compressed gas,and the alternate high air pressure can be recovered.The structure of the system and working principle of the presented harvester were introduced,and the theoretical and experiment were analyzed.The theoretical analysis results showed that the piezoelectric plate had high bearing capacity and it can collect the compressed gas energy effectively.The piezoelectric harvester was subjected by various parameters such as compression volume and compression speed.The expected effect can be adjusted by changing different parameters.The diameter and thickness of piezoelectric unimorph were 12 mm and 0.2 mm,respectively.The diameter and distance of cylinder were 63 mm and 150 mm and the prototype were fabricated.The test system was built to research the rules and performances of piezoelectric array energy harvester.In the test,the pressure,cycle and flow were adjusted.Experimental results showed that the output voltage was simultaneously increased with the increase of flow when the pressure was fixed.With the increase of parallel number of piezoelectric plates,the output power was increased either.It had optimal effect when the five piezoelectric plates were parallel connected.The optimal load resistance was 3 MΩ and instantaneous power was 6.53 μW under the five piezoelectric plates parallel.关键词
