ABSTRACT:
An apparatus for detecting a static field includes two surfaces of conductive material that are (i) electrically coupled to each other, and adjacent to each other. The two surfaces repel each other in the presence of a static field. The conductive material has a deformation property such that stress caused by repulsion of the two surfaces from each other by at least a predetermined distance causes at least one of the surfaces to permanently deform.
