Abstract:
1. A micromechanical acceleration sensor, comprising: a substrate having a substrate plane; an elastic diaphragm having a diaphragm plane and extending parallel to the substrate plane and at least partially connected to the substrate, wherein the diaphragm has a surface region, delimited by an outer periphery, configured to be deflected perpendicular to the substrate plane; and a seismic mass having a center of gravity situated outside the diaphragm plane, wherein the seismic mass extends at a distance over regions of the substrate situated outside the outer periphery of the surface region of the elastic diaphragm, wherein a system composed of multiple electrodes is provided on the regions of the substrate situated outside the outer periphery of the surface region of the elastic diaphragm and coplanar with the diaphragm plane, each electrode and a corresponding oppositely situated region of the seismic mass forming a capacitor in a circuit, and wherein a central region of the seismic mass is attached at an attachment region to the elastic diaphragm in the surface region of the elastic diaphragm configured to be deflected perpendicular to the substrate plane.
