Abstract:
1. A microelectromechanical structure, comprising: a substrate; a proof mass, suspended above the substrate, the proof mass responding to acceleration by displacing and tilting with respect to a moveable mass rotational axis that is located in the plane of the proof mass; at least one anchor, fixed on the substrate, the at least one anchor being coupled to support the proof mass; and a plurality of elastic elements, connected to the at least one anchor and the proof mass, geometry and configuration of the plurality of elastic elements being adjusted to reduce a displacement of the proof mass caused by thermo-mechanical stress with respect to the moveable mass rotational axis, wherein a first subset and a second subset of the plurality of elastic elements are arranged to support the proof mass from two opposite sides, and the first and second subsets of elastic elements mirror each other in their geometry and configuration with respect to a central line that is perpendicular to the moveable mass rotational axis and passes a center of the proof mass.
