Abstract

The invention provides a glass-metal-blown miniature hemispherical resonant gyroscope and a manufacturing method thereof. The gyroscope comprises a cuboidal silicon base, a hemispherical shell type central resonator and eight electrodes, wherein the eight electrodes are uniformly distributed around the central resonator, consist of four drive electrodes and four detection electrodes and are connected to pins through leads; the drive electrodes and the detection electrodes can achieve electrostatic drive and detection through applying positive and negative voltage to corresponding pins; the central resonator and the hemispherical shell type electrodes are manufactured by adopting a glass metal blowing process. The gyroscope adopts an MEMS (Micro-Electromechanical Systems) process for processing, is simple in structure, small in volume and relatively high in accuracy, and has great development prospects.

Description

technical field [0001] The invention relates to a solid wave mode matching gyroscope in the field of micro-electromechanical technology, in particular to a glass-metal blown micro hemispherical resonant gyroscope and a preparation method thereof. Background technique [0002] Gyroscope is an inertial device that can be sensitive to the angle or angular velocity of the carrier, and it plays a very important role in the fields of attitude control, navigation and positioning. With the development of national defense technology and aviation and aerospace industries, the requirements of inertial navigation systems for gyroscopes are also developing in the direction of low cost, small size, high precision, multi-axis detection, high reliability, and adaptability to various harsh environments. The micro gyroscope based on MEMS technology is processed by batch manufacturing technology, its cost, size, and power consumption are very low, and its environmental adaptability, working li...
