Abstract: A MEMS device includes a substrate, a set of spring, and a proof mass suspended above and coupled to the substrate by the springs. Each spring includes a corresponding anchor on the substrate and a beam extending away from that anchor. Each beam has a fixed end that is coupled to the anchor by a first linkage at one end of the beam proximal to the anchor and a free end that is coupled to the proof mass by a second linkage at an end of the beam that is distal to the anchor. The anchors are arranged symmetrically around a center of the proof mass. The proof mass translates vertically with respect to the substrate and when a vertical displacement of the proof mass toward the substrate reaches a predefined value, the free end of each spring contacts the substrate and prevents the proof mass from contacting the substrate.

Further, a spring anchor is coupled to another end of the first beam. In response to the proof mass moving, an extension coupled to the rigid structure moves in an opposite direction to motion of the proof mass to contact the proof mass and stop the movement of the proof mass.
