Patent ID: 8555719

Claim:
A microelectromechanical systems (MEMS) sensor comprising: a substrate; a movable element positioned in spaced apart relationship above a surface of said substrate, said movable element being adapted for motion relative to a rotational axis positioned between first and second ends of said movable element; a suspension anchor formed on said surface of said substrate, a centroid of suspension anchor being located at said rotational axis; a first folded torsion spring interconnecting said movable element with said suspension anchor, said first folded torsion spring having a first end coupled to said suspension anchor; and a second folded torsion spring interconnecting said movable element with said suspension anchor, said second folded torsion spring having a second end coupled to said suspension anchor, said first and second folded torsion springs having a substantially equivalent shape, said second folded torsion spring being generally oriented in rotational symmetry relative to said first folded torsion spring about said centroid of said suspension anchor, and each of said first and second ends of said first and second folded torsion springs being displaced away from and on opposite sides of said rotational axis by a substantially equivalent distance.
