    摘要:

    提出了一种基于压电效应的人体动能转换装置(压电俘能器),并对其发电能力进行了理论和试验分析。结果表明,在一定变形范围内,压电俘能器的输出电能随着激励力的增加而增大;当激励频率和压电俘能器结构尺寸确定时,压电俘能器的输出功率随着负载电阻的变化而变化,且存在最佳的负载使其输出功率达到最大值,最大输出功率是压电俘能器开路时电压和电容的函数,最大输出功率与外接滤波电容无关。在2 Hz(行走频率)激振频率下,压电俘能器最大输出功率为0.31 mW。

    Abstract:

    A piezoelectric energy harvester (PEH) for converting the kinetic energy of human body based on the piezoelectric effect was proposed,and the power generating capacity of the device was studied theoretically and experimentally.The results showed that the output energy of the PEH increased with increasing excitation force in a certain range of deformation. When the excitation frequency and the PEH structure size was determined,the output power of the PEH changed along with the load of different resistance value,and there was an optimal load to obtain maximal electrical energy.The maximum output power was the function of voltage and capacitance in open circuit of PEH,The maximum output power was unrelated with the external filter capacitor.The maximum output power of the PEH was 0.31 mW at excited frequency of 2 Hz (the walking frequency).
