Classification: CPC G | IPC G

Claim 0:
1. A sensor device, comprising:
a substrate;
at least one electrical insulation layer on the substrate;
an edge structure that is disposed on the at least one electrical insulation layer and delimits an internal region above the substrate;
a membrane that is anchored on the edge structure and at least partly spans the internal region, the membrane encompassing, in the internal region, a region movable by a pressure;
a first intermediate carrier that extends in the movable region below the membrane and is electrically and mechanically connected to the membrane by contact points, the membrane being able to be stiffened by the first intermediate carrier, and the first intermediate carrier representing a movable electrode, and encompasses at least one spacing element that extends from the intermediate carrier toward the substrate in a region below the contact points; and
a first counter electrode on the at least one electrical insulation layer,
the first counter electrode extending under the intermediate carrier, and a first distance between the intermediate carrier and the first counter electrode being modifiable by the pressure on the movable region, and the first counter electrode encompassing, under the intermediate carrier, at least one electrically separated region that is disposed below the spacing element and has at least a lateral extent of the spacing element.
