    Abstract

    A sensing device for measuring force and/or torque includes a top part with a top electrode structure, a bottom part with a bottom electrode structure, and a support structure. The support structure includes spring elements for supporting the top part on the bottom part with the top electrode structure parallel to and facing the bottom electrode structure. The spring elements provide a gap between the top and bottom electrode structures and allow displacement of the top part relative to the bottom part in three orthogonal directions two parallel and one perpendicular to the bottom plate, and for rotation of the top part relative to the bottom part around three orthogonal axes, corresponding with said two parallel and one perpendicular directions.; The displacement and/or rotation induce a change in distance between and/or overlap area of the top and bottom electrodes and a corresponding change of capacitance.
