Abstract

An apparatus has been fabricated to measure the admittance of a PZT bar in rotation. The rotation sensitivity of admittance of soft PZT and hard PZT bars has been detected at the rate of several thousand revolutions per minute, using an Impedance Analyzer. It has also been confirmed that the hard PZT bar has higher rotation sensitivity of the admittance than the soft PZT bar. The authors note that their experimental results suggest the possibility of developing a gyroscope based on rotation sensitivity of admittance of PZT ceramics.
