Micromechanical sensor element

A micromechanical sensor element, comprising:

• a substrate;
• a first movably arranged structure movably arranged on the substrate;
• a second movably arranged structure movably arranged on the substrate;
• and
• a substrate-fixed electrode arrangement situated on the substrate in a fixed manner, the substrate-fixed electrode arrangement including at least one first electrode;
• wherein:
• the first movably arranged structure and the second movably arranged structure are coupled with each other by coupling elements in such a way that, upon a deflection of the first movably arranged structure along a first direction running in parallel to the substrate, a portion of the second movably arranged structure undergoes a deflection along an opposite direction;
• the at least one first electrode includes a plurality of electrode surfaces;
• the first movably arranged structure includes a plurality of first movable electrode surfaces, and the second movably arranged structure includes a plurality of second movable electrode surfaces;
• the plurality of electrode surfaces of the substrate-fixed electrode arrangement and the first and second movable electrode surfaces of the first and second movably arranged structures engage with each other;
• the first movable electrode surfaces of the first movably arranged structure and the second movable electrode surfaces of the second movably arranged structure being each situated on sides of the plurality of electrode surfaces of the substrate-fixed electrode arrangement facing away from the first and second movably arranged structures,
• wherein:
• the at least one first electrode includes a first electrode section and a second electrode section;
• the first electrode section and the second electrode section are connected to the substrate via a shared first anchor point, wherein a displacement of the shared first anchor point relative to another anchor point results in distances between electrode surfaces of the first electrode section and the first movable electrode surfaces increasing, while distances between electrode surfaces of the second electrode section and the second movable electrode surfaces decrease;
• the first electrode section faces the first movably arranged structure, and the second electrode section faces the second movably arranged structure.
