Abstract
The invention relates to a microelectromechanical structure, and more particularly, to systems, devices and methods of compensating the effect of the thermo-mechanical stress by incorporating and adjusting elastic elements that are used to couple a moveable proof mass to anchors. The proof mass responds to acceleration by displacing and tilting with respect to a moveable mass rotational axis. The thermo-mechanical stress is accumulated in the structure during the courses of manufacturing, packaging and assembly or over the structure's lifetime. The stress causes a displacement on the proof mass. A plurality of elastic elements is coupled to support the proof mass. Geometry and configuration of these elastic elements are adjusted to reduce the displacement caused by the thermo-mechanical stress.
