1. A method for reducing undesired movements parallel to a plane of a substrate of proof masses in micro-electromechanical systems (MEMS) devices, the proof masses being suspended above the substrate by one or more suspensions, said method comprising:

  • providing a rotationally compliant anchor on the substrate substantially between a first proof mass and suspensions for the first proof mass and a second proof mass and suspensions for the second proof mass;

    coupling a first portion of a beam to the first proof mass;

    coupling a second portion of the beam to the second proof mass; and

    attaching a third portion of the beam directly to the anchor, the third portion extending between the first portion and second portion of the beam and extending across a top of the anchor the anchor and the third portion configured to allow at least a partial rotation of the third portion of the beam about an axis perpendicular to the substrate.
