Abstract
We developed piezoelectric MEMS gyrosensors composed of PZT thin films. The PZT thin films were directly deposited on the microfabricated metal cantilevers by RF sputtering method.To evaluate basic performance of the gyrosensor,we measured resonance frequency of horizontal and vertical directions.We clearly observed horizontal and vertical resonances at 48.46kHz and 28.77 kHz respectively.Then we calculated the sensitivity analytically.
