Patent ID: 8826735

Claim:
A device for resonantly driving a micromechanical system, comprising: at least one seismic mass supported by at least one spring; at least one drive for driving a vibration of the seismic mass; at least one element that is motionally coupled to the seismic mass; at least one detection element for detecting a relational parameter, between the motionally coupled element and the detection element, that is changeable with the vibration of the seismic mass; wherein the detection element is equipped to cause an interruption of the vibration drive when a predetermined value of the relational parameter is reached; wherein the detection element and the motionally coupled element each have a tunnel tip, which form a tunnel bridge for electric current, via which, at a predetermined approach of the two tunnel tips, a predetermined tunnel current flows, which has the effect of switching an interruption switch, interrupting the vibration drive.
