Systems and methods for an inertial sensor suspension that minimizes proof mass rotation

摘要

The present invention generally relates to systems and methods for an inertial sensor suspension that minimizes proof mass rotation and translation. The system contains a microelectromechanical sensor (MEMS) device for measuring rotation along an input rotation axis. The MEMS device includes at least one substrate, at least one proof mass, and a suspension system. The suspension system includes at least one flexure connecting the at least one proof mass to a substrate and at least one anchored suspension element with a split support beam having a first split portion and a second split portion. The first split portion and the second split portion are of curved shape.
