Abstract
A sensor device comprising a first substrate and a second substrate arranged in a planar manner at a distance to each other. A first electrode on an inner side a first substrate. A second electrode on an inner side of a second substrate. A first force sensitive element on the inner side of the first substrate and covering at least a part of the first electrode. A second force sensitive element on the inner side of the first substrate and covering at least part of the second electrode. The sensor device further comprises a plurality of outer stiffening elements arranged on at least one of the first substrate or the second substrate at an outer area of the sensor device, and a plurality of inner stiffening elements arranged on at least one of the first substrate or the second substrate (S2) on an inner area of the sensor device.

A sensor device comprising:
- a first substrate and a second substrate arranged in a planar manner at a vertical distance to each other, wherein inner sides of the first substrate and the second substrate face each other;
- a first electrode arranged on the inner side of the first substrate;
- a second electrode arranged on the inner side of the second substrate;
- a first force sensitive element arranged on the inner side of the first substrate and covering at least a part of the first electrode;
- a second force sensitive element arranged on the inner side of the second substrate and covering at least part of the second electrode;
- a plurality of outer stiffening elements, each arranged on at least one of the first substrate or the second substrate, the plurality of outer stiffening elements being radially arranged around a center axis of the sensor device and located in an outer area of the sensor device, the outer area being an area closer to an outer edge of the sensor device than to the center axis;
- and
- a plurality of inner stiffening elements, each arranged on at least one of the first substrate or the second substrate, the plurality of inner stiffening elements being radially arranged around the center axis of the sensor device and located on an inner area of the sensor device, the inner area being an area closer to the center axis than to the outer edge, and wherein
- the first force sensitive element and the second force sensitive element are arranged radially between the plurality of inner stiffening elements and the plurality of outer stiffening elements.
