摘要： A micromechanical enclosure suitable for micromechanical sensors, particularly acceleration sensors in the field of automotive vehicles, includes a micromechanical structure on a substrate, a conductor track layer connected to the micromechanical structure on the main surface of the substrate, a cover that covers a part of the main surface of the substrate, and a level compensation layer arranged next to the conductor track layer beneath the contact area during the manufacture of the wafer. A planarizing layer, which forms a level surface, may additionally be applied above this, to form a level area on the substrate which can easily be joined to a level area of the cover by means of a metallic wafer bond. This achieves small overall dimensions and avoids a glass frit bond.

摘要： A system for measuring acceleration in three axes comprises four individual sensors arranged in a rectangle on a common substrate with each having one main sensitivity axis. Each individual sensor has a seismic mass in the form of a cantilevered paddle connected by a bending beam to an outer frame and having a center of gravity. Each beam is arranged parallel to the substrate surface and each contains means for measuring the bending that occurs when acceleration forces act upon the system. The actual acceleration occurring on each axis can then be determined as a function of the error angle formed between the sensitivity axis and the normal to the substrate surface.

摘要： A self-testing sensor (especially to measure an angular rate or acceleration) includes a resonant structure, an actor unit configured to excite the structure to a first periodic vibration, a piezoresistive element configured to generate an output signal that depends on the measured quantity, and an isolator configured to isolate a test signal component from the output signal, whereby the test signal component is generated by a second periodic vibration of the structure superposed on the first vibration. A device for self-testing a sensor includes an isolator configured to isolate a test signal component superposed on a useful signal component from the periodic output signal of the sensor, and it includes a comparator configured to compare the test signal component with a predefined value or a test signal fed to the sensor. For the self-test, a second periodic vibration is superposed on a first vibration of the structure, and an output signal containing information on the measured quantity is determined. A test signal component contained in the output signal is monitored.

摘要： 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.

摘要： 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.
