Gyroscope with peripheral detection

A gyroscope comprises four Coriolis masses arranged around a center point where a lateral axis crosses a transversal axis orthogonally in the device plane. The first and second masses are aligned on the lateral axis, and the third and fourth masses are aligned on the transversal axis. The gyroscope further comprises four pairs of elongated mass elements. The mass elements of the first pair are transversally aligned on opposite sides of the lateral axis outside of the first mass. The mass elements of the second pair are transversally aligned on opposite sides of the lateral axis outside of the second mass. The mass elements of the third pair are laterally aligned on opposite sides of the first transversal axis outside of the third mass. The mass elements of the fourth pair are laterally aligned on opposite sides of the first transversal axis outside of the fourth mass.

MEMS GYROSCOPE

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.

Methods for fabricating MEMS tuning fork gyroscope sensor system using silicon wafers. This provides the possibly to avoid glass. The sense plates can be formed in a device layer of a silicon on insulator (SOI) wafer or in a deposited polysilicon layer in a few examples.

MEMS GYROSCOPE HAVING AN IMPROVED REJECTION OF THE QUADRATURE ERROR

The MEMS gyroscope is formed by a substrate, a first mass and a second mass, wherein the first and the second masses are suspended over the substrate and extend, at rest, in a plane of extension defining a first direction and a second direction transverse to the first direction. The MEMS gyroscope further has a drive structure coupled to the first mass and configured, in use, to cause a movement of the first mass in the first direction, and an elastic coupling structure, which extends between the first mass and the second mass and is configured to couple the movement of the first mass in the first direction with a movement of the second mass in the second direction. The elastic coupling structure has a first portion having a first stiffness and a second portion having a second stiffness greater than the first stiffness.
