摘要
利用制备的压电厚膜采用简支支撑方式,设计和制作了压电发电装置,并对该发电装置进行了压电发电实验研究.实验结果表明,单片压电厚膜在外加作用力频率从0~2 Hz发生变化时,在负载电阻值为105 kΩ时可获得约130μW的最大输出电功率.研究中还发现增加并联的厚片数目可成比例地增加输出功率,因此能满足用于无线车辆检测传感器的功率要求.
A piezoelectric generator was designed using piezoelectric thick film supported by simply-supported beam, and then research on experiments of the performance of the piezoelectric generator was carried out. The ex- periment result showed that the maxim output power was 130μW as the load resistance was 105 kΩ by single piezoelectric thick film with force frequency varying from 0 to 2 Hz. Study also found that the output power increase was proportional to the number of slabs in parallel, thus could satisfy the power requirements of wireless vehicle detection sensor.
