    • 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).
    • 本发明涉及一种微机械加速度传感器,其包括基板(1),平行于基板平面延伸的弹性膜(5),其部分地连接到基板,并且包括可以垂直于 基板平面。 本发明还包括其中重心位于弹性膜(5)的平面外的地震块(6)。 地震块(6)在位于弹性膜(5)的区域外侧的衬底区域上延伸一段距离,并且包括由多个电极(3a,3b,3c,3d)构成的装置,其形成 在电路中具有地震块(6)的相对区域的电容器。 在中心区域,将抗震块(6)紧固在弹性膜(5)的垂直于基板平面的挠曲面的表面区域上。
