Device for measuring an electric field

A device for measurement of an electric field, the device comprising a micromechanical structure, which extends in a first direction, a second direction and a third direction;

• wherein the first direction, the second direction and the third direction are mutually normal to one another;
• wherein the micromechanical structure is made from a material that is electrically conducting at an operating temperature and has a frame portion as well as a movable portion;
• wherein the movable portion is connected in electrically conducting and mechanically elastic manner with the frame portion and is movable relative to the frame portion;
• wherein the micromechanical structure is so designed that, in the case of an arrangement of the micromechanical structure in the electric field with a non-zero first field-strength component parallel to the first direction, an electrical polarization of the micromechanical structure takes place, which results in a first force component acting on the movable portion parallel to the first direction as well as a change, dependent on the first force component, of the spatial arrangement of the movable portion relative to the frame portion;
• and
• wherein detecting means are provided in order to determine the change of the spatial arrangement of the movable portion relative to the frame portion.
