Abstract
A sensor for capacitive detection of a mechanical deflection includes a substrate having a first substrate electrode and a second substrate electrode; and a mass movable relative to the substrate. The mass is divided into: a first electrically separate region having a first ground electrode; and a second electrically separate region of the mass having a second ground electrode. At least one portion of the first ground electrode is situated in a first region between the first substrate electrode and the second substrate electrode, and forms a first differential capacitor. At least one portion of the second ground electrode is situated in a second region between the first substrate electrode and the second substrate electrode, and forms a second differential capacitor.
