Patent ID: 7637160

Claim:
A MEMS device having a sensitivity to a stimulus in at least one sensing direction, comprising: a substrate; a movable mass suspended in proximity to the substrate, wherein the movable mass has corner portions; at least one suspension structure coupled approximately to the corner portions of the movable mass for performing a mechanical spring function; at least one anchor for coupling the substrate to the at least one suspension structure, wherein the at least one anchor is positioned approximately on a center line in the at least one sensing direction, wherein the at least one suspension structure is formed by a set of n segments that extend completely between the movable mass and the at least one anchor, wherein n is at least three and an odd integer, the segments being generally parallel to one another, each segment being generally straight and having two ends, each of the ends being coupled to one of the movable mass, the at least one anchor, or another segment end; and at least one suspension link positioned on the at least one suspension structure for controlling the sensitivity of the MEMS device.
