摘要

近年来，利用压电元件从环境振动和人体运动中获取能量已成为人们关注的热点。本研究量化了压电装置从振动环境和人体运动中产生的能量。镍氢可充电电池已被用于储存所产生的能量。在整个实验过程中，放电后的40mAh可充电电池在谐振振动下可以在不到10分钟的时间内充电到电池电压。同时，在人体运动能量收集实验中，受试者以5km/h的速度奔跑，放电的40mAh可充电电池可在1小时内充电至电池电压。

Development of energy harvesting device using piezoelectric material

Using piezoelectric elements to harvest energy from ambient vibration and human motion has been of great interest recently. This study quantifies the amount of energy generated by piezoelectric device from vibration environment and human motion. Nickel metal hydride rechargeable battery has been used to store the energy generated. Throughout the experiment, the discharged 40mAh rechargeable battery can be charged to its cell voltage in less than 10 minutes in resonant vibration. Meanwhile, for human motion energy harvesting experiment, as subject running with 5km/h speed, the discharged 40mAh rechargeable battery can be charged to its cell voltage in one hour.
