US Patent 11892467 Accelerometer with translational motion of masses

A microelectromechanical systems (MEMS) accelerometer is provided, comprising a substrate disposed in a plane defined by a first axis and a second axis perpendicular to the first axis; a first proof mass and a second proof mass coupled to the substrate and configured to translate in opposite directions of each other along a third axis perpendicular to the first and second axes; and at least one lever coupling the first proof mass to the second proof mass, wherein, the MEMS accelerometer is configured to detect acceleration along the third axis via detection of translation of the first and second proof masses along the third axis; and the MEMS accelerometer exhibits symmetry about the first and second axes.
