摘　　要：利用压电陶瓷发电特性,将轮胎行进中的挤压作用作为压电发电的动力来源,设计了一种能用于汽车轮胎压力监测系统(TPMS)的压电发电装置。这种压电发电装置体积小,重量轻,无需经常更换,实验中所获得的能量完全能满足TPMS的无源化要求。这种基于压电陶瓷的发电方案是TPMS无源化的一种比较理想的解决途径。In this paper,making use of power generation characteristics of piezoelectric ceramics and taking the squeezing effect in the process of the tire moving as the power source of piezoelectric power generation,a piezoelectric device for automobile tire pressure monitoring system（TPMS） was designed.This device has many characteristics,such as small size,light weight,no need to be frequently changed,the energy sufficient obtained in the experiment to meet the requirements of TPMS passive.This generation based on piezoelectric ceramic is an ideal solution for passive TPMS.
