    摘要: A MEMS sensor includes a movable element positioned in spaced apart relationship above a surface of a substrate and a single centrally located suspension anchor formed on the surface of the substrate. First and second rigid beams are coupled to opposing sides of the suspension anchor and are suspended above the surface of the substrate. A first torsion spring is interconnected between the movable element and the first rigid beam, and a second torsion spring is interconnected between the movable element and the first rigid beam. The rigid beams and the torsion springs are stiff in a lateral direction relative to the surface of the substrate so as to limit slide displacement of the movable element under the condition of a multi-directional overload situation.

    摘要: A technique is provided for determining a force/acceleration acting on a proof mass of a bistable device. According to a first aspect of the invention, the location of a boundary of one of the stable configurations of the device is monitored and compared to a predetermined location of the same boundary corresponding to a condition in which the force/ acceleration is absent, to detect a deviation of said location. The deviation is used to determine the force/acceleration. According to another aspect of the invention, the resonance frequency of the proof mass oscillation in one of the stable regions is monitored, and compared to a predetermined resonance frequency of the proof mass oscillation in the same region corresponding to a condition in which the force/acceleration is absent, to determine a deviation of the resonance frequency due to the presence of force/acceleration. The deviation in the resonance frequency is used to determine the force/acceleration.
