Jie Meng , Sun Xiaofeng , Jiang Delong , Zhang Guangchao

ABSTRACT:The structure of piezoelectric power generation device on tire pressure monitoring system was put forward in this paper. The formula for the energy output of the piezoelectric generator was solved. The natural frequency of the power generation device and the frequency of the external excitation can be matched by adjusting the quality of the mass block to improve the power generation capability.
