Abstract:
1. A micromechanical sensor element for providing capacitive differential pressure detection, whose structural elements are implemented in a layered structure, comprising: two pressure connections that are separated from each other; a deflectable carrier element for at least one deflectable measuring electrode; at least one stationary counter electrode for the measuring electrode; wherein the carrier element spans a closed cavity in the layered structure, wherein the carrier element is spanned by a cap structure, wherein the carrier element is suspended on the cap structure via a suspension web functioning as a rocker bearing, wherein the two pressure connections are connected to the top side of the carrier element, which is divided by the suspension web into two pressure connection zones which are separated from each other, and wherein the at least one measuring electrode is situated on the underside of the carrier element and the at least one counter electrode is situated on the opposite wall of the cavity.
