Classification: CPC B  G | IPC B  G

Claim 0:
1. A micromechanical structure, comprising:
a substrate;
a seismic mass movable with respect to the substrate;
a first detector; and
a second detector;
wherein a first direction and a second direction, which is perpendicular to the first direction, define a main extension plane of the substrate, the first detector is configured for detecting a translatory deflection of the seismic mass in the first direction, and the second detector is configured for detecting a rotatory deflection of the seismic mass about a rotation axis, the rotation axis being situated in the second direction;
wherein the seismic mass is connected to the substrate via an anchoring element and four torsion spring sections situated along the second direction, the first detector includes an electrode structure including first electrodes attached at the seismic mass and second electrodes attached at the substrate, the first electrodes and the second electrodes having a two-dimensional extension in the second direction and in a third direction, the third direction being perpendicular to the main extension plane, the anchoring element including a first section and a second section, a gap being provided between the first section and the second section in the first direction, a connecting element connecting two of the first electrodes, and the connecting element being guided through the gap in the second direction,
wherein the connecting element includes at least one first elevation, a distance between the connecting element and the substrate being decreased in an area of the first elevation, compared to a distance between the connecting element and the substrate outside the first elevation.
