Driving the Accelerometer by Vibration Power Generation using Parallel-type Laminated Piezoelectric Elements

Abstract

An electrical power generating device using piezoelectric element (PZT) has been developed to convert vibration energy into electrical energy for the application of monitoring of infrastructure and buildings.

In this paper experiments of driving the accelerometer module using parallel-type laminated PZT elements under vibration load and the evaluation of comparison of driving frequency of the accelerometer module of single laminated PZT and parallel-type laminated PZT are reported. Such types of power generator were shown to be useful for the driving sensor and monitoring system.
