A micromechanical capacitive acceleration sensor is described for picking
up the acceleration of an object in at least one direction. The sensor
includes a frame structure (110), a sensor inertia mass (101) made of a
wafer and movably mounted relative to the frame structure (110) about a
rotation axis, and a capacitive pick-up unit (120) for producing at least
one capacitive output signal representing the position of the sensor mass
(101) relative to the frame structure (110). The sensor inertia mass
(101) has a center of gravity which offset relative to the rotation axis
in a direction perpendicularly to a wafer plane for measuring
accelerations laterally to the wafer plane. The sensor mass (101) and the
frame structure (110) are made monolithically of one single crystal
silicon wafer. A cover section (112) forms a common connector plane (150)
for the connection of capacitor electrodes (125,126). Torqueable elements
(105) form an electrically conducting bearing device for the sensor mass
(101).
