Abstract
An accelerometer includes a substrate. The substrate includes anchor points. An external coupling unit is annular and is parallel to the substrate. A first torsion plate is disposed on an inner side of the external coupling unit and is connected to the anchor points. Inner coupling beams are disposed on a side, close to the anchor points, of the first torsion plate. A second torsion plate is disposed on the inner side of the external coupling unit and is connected to the anchor points, the second torsion plate is connected to the first torsion plate through two of the inner coupling beams, the second torsion plate and the first torsion plate are mutually embedded, the first torsion plate and the second torsion plate are symmetrical about a first axis of symmetry. The accelerometer reduces cross coupling reduced, and accuracy and anti-interference performance of the accelerometer are improved.
