摘要
为利用压电材料收集人体能量,设计了一种人体能量收集系统,它可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电陶瓷片参与发电,另外还设计了压电发电装置的能量存储与控制电路,并实验了其发电特性,该装置适合给假肢或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 was fixed at the knees of people,was designed to press piezoelectric ceramics （PZT） in order to collect the energy created by walking people. The energy harvester selectively engaged power generation at the end of the swing phase. A piezoelectric generator was designed. The electrical energy generation performance was investigated experimentally. This method well-suited for charging powered prosthetic limbs and other portable medical devices.
