摘要： The capacitive sensor for detecting the movement of an object, particularly for detecting the actuation of a key of an operating unit, is furnished with a first electrode (30; 32) and a second electrode (34; 36) which is provided for connection or mechanical coupling to or arrangement on the object, the distance of which second electrode from the first electrode changes (30; 32) when the object moves. The two electrodes (30, 34; 32, 36) form a first capacitor (26; 28) with a volume (40) between the electrodes (30, 34; 32, 36), the size of which changes when the object moves. An evaluation unit (38), which is connected to the two electrodes (30, 34; 32, 36) and determines a change of capacitance between the two electrodes (30, 34; 32, 36) resulting from a change of their spacing and volume, is further provided. A deformable, non-gaseous first dielectric (42) is arranged between the two electrodes (30, 34; 32, 36). The first dielectric (42) defines at least one gas volume (44) or, together with at least one of the two electrodes (30, 34; 32, 36) defines a gas volume (44) that is filled by a gaseous second dielectric, wherein at least a part of the second dielectric escapes from the gas volume (44) and from the volume (40) between the two electrodes when the two electrodes (30, 34; 32, 36) approach one another, and, when the two electrodes (30, 34; 32, 36) approach one another, the portion of the volume (40) between the two electrodes (30, 34; 32, 36) occupied by the first dielectric (42) increases and the portion of the volume (40) between the two electrodes (30, 34; 32, 36) occupied by the second dielectric decreases.

摘要： A MEMS tunable capacitor comprises first and second opposing capacitor electrodes (10,12), wherein the second capacitor electrode (12) is movable by a MEMS switch to vary the capacitor dielectric spacing, and thereby tune the capacitance. A tunable dielectric material (14) and a non-tunable dielectric material are in series between the first and second electrodes. The tunable dielectric material occupies a dimension gd of the electrode spacing, and the non-tunable dielectric material occupies a dimension g of the electrode spacing. A third electrode (20) faces the movable second electrode (12) for electrically controlling tunable dielectric material. A controller is adapted to vary the capacitor dielectric spacing for a first continuous range of adjustment of the capacitance of the MEMS capacitor, and to tune the dielectric material (14) for a second continuous range of adjustment of the capacitance of the MEMS capacitor, thereby to provide a continuous analogue range of adjustment including the first and second ranges. This arrangement provides independent control of the MEMS function and the dielectric tuning function, and enables a continuous adjustability.

摘要： A variable capacitance element includes a movable element provided above a substrate using supporting portions and support beams so as to be displaced from the substrate. An insulating film and a movable electrode are provided on a conductor facing surface of the movable element. A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.
