    • The invention relates to a micromechanic acceleration sensor, comprising a substrate (1), an elastic membrane (5), which extends in parallel to the substrate plane, is partially connected to the substrate and comprises a surface region, which can be deflected perpendicular to the substrate plane. The invention further comprises a seismic mass (6), wherein the center of gravity thereof is outside of the plane of the elastic membrane (5). The seismic mass (6) extends at a distance across substrate regions, which are located outside of the region of the elastic membrane (5) and comprise an arrangement made of a plurality of electrodes (3a, 3b, 3c, 3d), which form a capacitor with opposing regions of the seismic mass (6) in a circuit. In the central region, the seismic mass (6) is fastened in the surface region of the elastic membrane (5), which can be deflected perpendicular to the substrate plane, to the elastic membrane (5).

    • The invention relates to a micromechanical component and a method for operating a micromechanical component. The micromechanical component comprises a stationary structure and a seismic mass, the stationary structure having first electrodes and the seismic mass having second electrodes. The seismic mass is mobile relative to the stationary structure in a main direction of movement that is parallel to the direct connecting line of the seismic mass with the stationary structure in a main plane of extension of the stationary structure. In a rest position of the seismic mass, the first electrodes and the second electrodes are interspaced in such a manner that there is no overlap of the first electrodes relative to the second electrodes in a first direction that is perpendicular to the main direction of movement in the main plane of extension and such an overlap only occurs in a state of deflection.
