Abstract:
Assembly of variable capacitance comprising a variable coverage or a variable distance of at least one first electrically conductive area and at least one second electrically conductive area, with said at least one first electrically conductive area being configured on or in a substrate and with said at least one second electrically conductive area being on or in an actuator element of a first micro-mechanical actuator that is disposed on said substrate in such a way that said first micro-mechanical actuator is capable of performing, by means of a first drive system, movement of said actuator element with said at least one second electrically conductive area along a surface of said substrate at different positions relative to said at least one first electrically conductive area at which positions said at least one second electrically conductive area overlaps said at least one first electrically conductive area at least partly; and holding means capable, by means of a second drive system independent of said first drive system, of pulling or pushing said actuator element in said different positions towards said substrate or a mechanical stop on said substrate and of holding said actuator element in such positions.
