Simulation and Experiment of Symmetrical Stacked Piezoelectric Energy Harvester in Water Hydraulic System
摘要
Abstract
With the rapid development of sensor technology and low-power electronic devices,environmental energy harvesting has become a primary research direction to replace traditional chemical battery power supplies.A symmetrical stacked piezoelectric energy harvester is proposed,offering a new approach for efficiently capturing energy in pipelines through structural innovation.A simulation analysis is conducted on the structure of the energy harvester and piezoelectric disk,exploring the velocity distribution,pressure changes,and mechanical response of the static structure inside the energy harvester,as well as the effects of static pressure,frequency,amplitude and resistance on the energy harvesting performance.The performance of series,parallel and hybrid connection methods for different piezoelectric elements is studied,and their output voltage,power and power density are compared.The results indicate that the difference in power generation between the two channels is small and generally consistent.It proves that an increase in the number of piezoelectric disks leads to an increase in output voltage and power,but the power density may decrease.关键词
