Abstract:
1. A micromechanical system for detecting an acceleration, comprising: a substrate; a rocker-like mass structure having a first lever arm and a diametrically opposed second lever arm, which are situated tiltably at a distance in relation to the substrate and about an axis of rotation to the substrate; and first and second electrodes situated on the substrate, each electrode being diametrically opposed to a lever arm, wherein the two electrodes are arranged in mirror symmetry with respect to the axis of rotation, wherein each lever arm includes a section extending from the axis of rotation, the two sections having varying masses that lie above an intermediate space between the electrodes and each section includes an end section having equal masses, such that the first electrode is located under the end section of the first lever arm and the second electrode is located under the end section of the second lever arm, each at a distance farther from the axis of rotation than the two sections having varying masses.
