Patent ID: 10712359

Abstract:
A flexure for a MEMS device includes an elongated beam and a protrusion element extending outwardly from a sidewall of the elongated beam. A MEMS inertial sensor includes a movable element spaced apart from a surface of a substrate, an anchor attached to the substrate, and a spring system. The spring system includes first and second beams, a center flexure between the first and second beams, a first end flexure interconnected between an end of the first beam and the anchor, and a second end flexure interconnected between an end of the second beam and the movable element. Each of the end flexures includes the elongated beam having first and second ends, and the sidewall defining a longitudinal dimension of the elongated beam, and the protrusion element extending from the sidewall of the elongated beam, the protrusion element being displaced away from the first and second ends of the beam.
