Abstract
A MEMS gyroscope includes an anchor point, at least two driving structures connected with the anchor point; a mass group connected with the driving structures, and coupling beams connected with adjacent driving structures. The mass group includes two detecting components arranged on opposite sides of the driving structures and connected with the driving structures. Each of the detecting components includes two mass blocks arranged at intervals and detecting transducers arranged below or above the mass blocks. The mass blocks are connected with the driving structures. At least portions of the mass blocks extend to outsides of the driving structures. The mass blocks and the detecting transducers are symmetrically arranged, which is convenient for realizing differential detection. In an out-plane oscillation mode, most portions of the mass blocks sense an angular velocity. By adopting detecting transducers, electromechanical coupling coefficient of detection is effectively improved, and sensitivity and signal-to-noise ratio are improved.
