Patent ID: 7343801

Claim:
A micromechanical capacitive acceleration sensor for picking up an acceleration of an object in at least one direction, said sensor comprising a sensor inertia mass having a center of gravity, a frame structure and a rotation axis movably supporting said sensor inertia mass in said frame structure, said sensor inertia mass comprising a first section forming a first part of a wafer defining a wafer plane in which said rotation axis extends, said sensor inertia mass comprising a second section forming a second part of said wafer and having a center of gravity determining configuration such that said center of gravity of said sensor inertia mass is positioned outside said rotation axis and outside said wafer plane in a direction perpendicularly to said wafer plane, said capacitive acceleration sensor further comprising at least one capacitive pick-up unit for producing at least one capacitive output signal representing a position of said sensor inertia mass relative to said frame structure.
