Deflectable micromechanical system and use thereof

A deflectable micromechanical system, comprising:

• a deflectable structure, including
• a deflectable element;
• a suspension element comprising at least one spring, the suspension element holding the deflectable element and having a deformation region for imparting deflection to the deflectable element, the deformation region being electrically conductive or semiconductive;
• a detector, the detector being designed as a piezoresistive sensor having first and second contacts, the first and second contacts being spaced apart from one another and being located on the deformation region;
• wherein the first and second contacts are connected to a voltage source to form an inhomogeneous electrical field in a depth direction perpendicular to contact surfaces of the first and second contacts so that the electrical resistance between the first and second contacts varies in dependence on a deflection of the deflectable element can be detected.
