Abstract
A micromechanical structure, in particular a micromechanical electric field meter as a thunderstorm warning device, for detection of an electric field, comprising a substrate having a principal extension plane, a first electrode, a second electrode, and a drive assemblage for producing a relative motion of the second electrode with respect to the first electrode into an overlapping position, the first electrode and the second electrode being, in the overlapping position, disposed above one another in a projection direction extending perpendicularly to the principal extension plane of the substrate, wherein the second electrode has a defined potential for shielding the first electrode with respect to the electric field in the overlapping position.
