Abstract

The invention discloses a novel piezoelectric gyroscope. The piezoelectric gyroscope comprises a base, a first beam structure for driving and a second beam structure for detecting which extend from the base are arranged oppositely, piezoelectric patches are respectively attached to the first beam structure and the second beam structure, the first beam structure is provided with a clamping portion on the end away from the base, the clamping portion is connected with the second beam structure in a clamping mode and the clamping portion can drive the second beam structure to do bending vibration. Compared with piezoelectric gyroscopes of relative technologies, the piezoelectric gyroscope is simple in process realization, convenient in modifying structure and size and big in frequency response of piezoelectric gyroscope.

Description

【Technical field】 [0001] The invention relates to the field of sensors, in particular to a piezoelectric gyroscope. 【Background technique】 [0002] The piezoelectric gyroscope in the related art adopts a single beam structure. Specifically, the single beam structure includes a metal sheet and a first piezoelectric sheet and a second piezoelectric sheet attached to two opposite side surfaces of the metal sheet, and the first piezoelectric sheet is only used as a drive, so The above-mentioned second piezoelectric sheet should be used as driving and detection at the same time, so very high precision is required in the process of process realization, so the process realization is very difficult. [0003] Therefore, it is necessary to propose a new technical solution to overcome the above-mentioned defects. 【Content of invention】 [0004] In order to solve the defect that the single-beam structure piezoelectric gyroscope in the related art is very difficult in process realiza...
