Abstract: A high-frequency MEMS switch comprises a signal conductor which is arranged on a substrate and an oblong switching element which has a bent elastic bending area and is fastened on the substrate in a cantilevered manner. An electrode arrangement generates an electrostatic force which bends the switching element toward the signal conductor. The switching element is arranged longitudinally parallel to the signal conductor, and has a contact area which extends transversely to the switch element over the signal conductor. Under the effect of the electrostatic force, the elastic bending area of the switching element progressively approaches the electrode arrangement in a direction parallel to the signal line. The switching element has, for example, two mutually parallel extending switching arms, which are mutually connected by a bridge as the contact area and are arranged on both sides of the signal line and parallel thereto.

A cover section (112) forms a common connector plane (150) for the connection of capacitor electrodes (125,126). Torqueable elements (105) form an electrically conducting bearing device for the sensor mass (101).

Abstract: A microsensor with a resonator structure, which is excited by first electrical signals to oscillate and emits second electrical signals in dependence on the measuring variable, wherein a heating element, supplied with at least one of the first electrical signals, is arranged on the resonator structure for the thermal excitations of oscillations. For the thermal excitation of lateral oscillations in a microsensor with a resonator structure, the microsensor is provided at one oscillating part of the resonator structure with at least two regions that are thermally separated by a zone with reduced heat conductance, and the heating element is arranged on one of the regions. This type of arrangements permits the excitation of the resonator structure to lateral oscillations if the heating element is supplied with corresponding current pulses. It is advantageous if a receiving element is arranged on at least one of the other regions to detect the oscillation amplitude.
