摘　　要：针对现有智能纺织品电源不能实时充电及携带不便等问题,提出基于压电式俘能技术和腿部运动相结合的面向智能纺织品自供电电源的能量俘获方法。通过对人体腿部运动姿态规律的分析,构建人体腿部运动简化机构的模型。并且设计了一种用于俘获人体腿部能量的弧形压电俘能器和能量收集电路,搭建了一种具有输出功率较高、能量损耗小、制造成本低的压电式人体腿部运动俘能装置。试验成功点亮LED灯,可以实现为一些低功耗的电子器件供电。Aiming at the problems that the existing smart textile power supplies cannot be charged in real time and inconve⁃nient to carry,an energy capture method for smart textile self-powered power supplies based on the combination of piezoelectric en⁃ergy capture technology and leg movement is proposed.Through the analysis of the posture law of the human leg movement,a model of the simplified mechanism of the human leg movement is constructed.An arc-shaped piezoelectric energy harvester and an energy harvesting circuit for capturing the energy of human legs are designed,and a piezoelectric energy harvesting device for human leg motions is built.The test successfully lights up the LED lights,which can be used to power some low-power electronic devices.
