Claim Text:
1. A microelectromechanical component comprising a semiconductor substrate, a cavity formed in the semiconductor substrate, which cavity is covered by a reversibly deformable membrane, wherein the membrane has portions in which material tensions of different strength occur during the deformation of the membrane, a sensor for detecting a deformation of the membrane, and a test actuator for deforming the membrane for test purposes, wherein the membrane, on an edge that comprises at least two opposite edge portions, is connected to the semiconductor substrate, wherein the material tensions generated in the membrane across the whole extension of the membrane during deformation of the membrane are greater along the edge of the membrane than at other portions of the membrane, wherein the test actuator is arranged at a site of a first edge portion of the membrane in which the material tension is maximal during deformation of the membrane, wherein the sensor is arranged at a site of a second edge portion of the membrane, and whereby a distance between the test actuator and the sensor along the edge of the membrane is maximized.
