摘要
为实现利用压电材料收集人体能量,将其转化成电能在某些特殊应用领域替代电池或自动为电池充电的目的,我们设计了一种人体能量收集系统,它可以在人行走过程中产生电能,该机构被安装在人腿的膝盖部位,选择性地在腿部摆动结束阶段连续地按压压电陶瓷片参与发电,它还能帮助关节完成减速动作,非常适合给假肢或者其他便携式医学设备充电。
An energy conversion system was developed to convert the human-body energy into electrical energy by means of the piezoelectric ceramic to substitute or charge automatically the battery under special conditions.This mechanism,which is fixed at the knees of people,is designed to press piezoelectric ceramics（PZT） in order to collect the energy created by walking people.The energy harvester selectively engages power generation at the end of the swing phase,thus assisting deceleration of the joint.this method well-suited for charging powered prosthetic limbs and other portable medical devices.
