英文摘要：

The criteria energy collection circuit based on piezoelectric effect was described,on which synchronized switch harvesting circuit of shunt inductor was designed.The math model of power was built by theoretic analysis and calculation in this paper.After the piezoelectric coupling analysis of ANSYS and simulation of MULTISIM,the result revealed that,comparatively with standard technique,the output voltage was increased by 100%,and the electrical power harvested could be increased by 400%.
