Abstract: For a sensor whose sensor structure is implemented in a micromechanical structural component and which has parts which are movable in relation to the stationary substrate of the structural component, and which also includes an unsupported a seismic mass, a spring system having at least one spring, the seismic mass being connected to the substrate through the spring system, and an overload protection to limit the deflection of the spring system and the seismic mass in at least one direction, and an arrangement for detecting the deflections of the spring system and the seismic mass, whereby the impact forces may be reduced to prevent conchoidal breaks and resulting incipient damage to the sensor structure, as well as formation of particles. To that end, at least one two-dimensional stop for at least one moving part of the sensor structure is provided as overload protection.

Abstract: A method for the electrical zero balancing of a micro mechanical component including a first capacitor electrode rigidly suspended over a substrate, a second capacitor electrode rigidly suspended over the substrate, and a third capacitor electrode disposed there between, resiliently and deflectably suspended over the substrate, as well as a differential-capacitance detector for measuring a differential capacitance of the capacitances of the variable capacitors configured in this manner. In this context, a first electric potential is applied to the first capacitor electrode; a second electric potential is applied to the second capacitor electrode; a third electric potential is applied to the third capacitor electrode; and a fourth electric potential is applied to the substrate. The fourth electrical potential applied to the substrate for the electrical zero-point balancing is changed for the operation of the differential-capacitance detector.
