Abstract:
1. A micromechanical acceleration sensor, comprising: a substrate; a suspension attached to the substrate by at least two anchors, wherein the two anchors determine a central axis; a seismic mass, wherein the seismic mass is suspended over the substrate with the aid of the suspension, and wherein the seismic mass has a mass center of gravity; and stationary capacitive electrodes; wherein the two anchors are situated on opposite sides of the mass center of gravity, a distance between the two anchors being less than an overall horizontal extension of the seismic mass along the central axis, wherein the seismic mass has recesses which are situated on opposite sides of the central axis and which are laterally open outward on sides facing away from the central axis, and wherein the stationary electrodes at least engage in the recesses of the seismic mass.
