A micromechanical sensor having an analyzer circuit and at least two detecting elements, each of the two detecting elements being connected to the analyzer circuit by at least one signal line. At least one signal line is connected to both detecting elements.

Micromechanical sensor having an analyzer circuit

An electronic device includes a resonant circuit and an evaluation circuit. The resonant circuit includes an acceleration-sensitive sensor which is excited to vibrate during a testing phase of the acceleration-sensitive sensor. The evaluation circuit is coupled to the resonant circuit to determine a performance reliability of the acceleration-sensitive sensor.

A piezoelectric force sensor includes a piezoelectric plate, with one electrode on each of the top and bottom sides of the plate. One of the electrodes is electrically connected via a conductor to a contact pad. In the case that the piezoelectric plate experiences breakage, the conductor is broken, and the remaining residual capacitance of the conductor and contact pad becomes so comparatively small that the breakage can be reliably detected.
