Accelerator sensor and accelerometer

Abstract

This disclosure discloses an acceleration sensor and an accelerometer, and the acceleration sensor includes a base, a cantilever, and a mass body fixed on the base through the cantilever, where the shape of the mass body is a centrally symmetric shape; and the cantilever includes four L-shaped arms, where the respective L-shaped arms include long arms connected with the base, and short arms connected with the mass body, and any adjacent two of the L-shaped arms are arranged symmetric to an axis. Since the cantilever includes the four symmetrically arranged L-shaped arms holding each other transversally, there is high transversal interference robustness, the structure is simple, and there is low fabrication difficulty.
