In order to solve the problem of highly sensitive detection of high overload micro gyroscope, a micro gyroscope structure with high sensitivity and high overload. The frequencies of the designed microgyroscope at the driving modal and detection modal are highly matched, thus the structure sensitivity are improved. The inplane detection appraoch is sdopted and the typical damping type of the driving and detection modals is synovial damping. The high Qfactor design of the micro gyroscope at atmospheric pressure is realized. The proposed microgyro adopts double cantilever beam design, thus the stability of the micro gyroscope structure is increased, and the antioverload ability is improved. The devicelevel simulation of the proposed microgyro show that its structural sensitivity is 53 nm/［（°）/s］ under the situations of about 100 000g（g=9.8 m/s2）of the computational overload capacity in driving direction and of about 70 000g of the computational overload capacity in detection direction.
