Sidewall piezoelectric-driven ring vibrating gyroscope and driving and detection method

The invention discloses a sidewall piezoelectric-driven ring vibrating gyroscope and its driving and detection method. The gyroscope comprises a resonant ring 1, a supporting spring 2, an anchor point 3 and a piezoelectric electrode 4. The piezoelectric electrode 4 is fixedly connected on a sidewall of the supporting spring 2, close to the anchor-point end; and the piezoelectric electrode 4 is used for excitation and detection of deformation of the resonant ring. The whole structure is simple and the detection method is convenient to operate. In comparison with a present ring vibrating gyroscope with a piezoelectric electrode arranged on the upper surface, the sidewall piezoelectric-driven ring vibrating gyroscope has characteristics of large driving displacement, high detection sensitivity, low energy consumption, small volume, impact resistance and the like.
