Abstract:
We have proposed a vibration gyroscope made of a single piezoelectric plate in plane motion. The gyroscope makes use of the degenerated modes associated with a square plate. In the present paper, the experimental verification using an enlarged piezoelectric ceramic plate is presented, whose results are compared with the numerical prediction based on two-dimensional and three-dimensional finite element modelling.
