Abstract
A MEMS single-axis gyroscope includes an anchor point structure, a sensing unit elastically connected with the anchor point structure, and a driving decoupling structure elastically connected with the anchor point structure and the sensing unit. The sensing unit includes a plurality of mass blocks arranged side by side and rocker connecting pieces. Each of the rocker connecting pieces is connected between corresponding two adjacent mass blocks. Connecting positions between each of the rocker connecting pieces and the corresponding two adjacent mass blocks are located on a same side of the line connecting the centers of the plurality of mass blocks. The MEMS single-axis gyroscope is able to perform differential detection, which resists interference of external electrical and mechanical noise, and improves a signal-to-noise ratio. By adjusting the rocker connecting pieces arranged between each two adjacent mass blocks, a total vector displacement of the plurality of mass blocks is zero.
