    摘要: 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).
