Device for measuring a force and/or torque

A device (10) for measuring a force (F) and/or torque (M) with a deformation body (10) comprising a first fastening element (11), a second fastening element (12) arranged in a direction (Z) at a distance from the first fastening element (11) and at least one length element (15) arranged between the two fastening elements (11, 12) and comprising a first end (15a), a second end (15b) and a length (L) along a longitudinal direction (R), wherein a force (F) acting on the deformation body (10) or a torque (M) acting on the deformation body (10) leads to a deformation of the length element (15), characterized in that an input-side input (21) of a mechanical amplifier (20) is fastened to the deformation body (10) by means of a coupling element (30), wherein a material measure (25) is arranged on an output-side output (22) of the mechanical amplifier (20) and a deformation of the length element (15) leads to a movement of the material measure (25), wherein the movement of the material measure (25) can be detected by a scanning element (40), wherein the device (1) comprises an evaluation unit (70), which is designed to evaluate the signals detected by the at least one scanning element (40) and to calculate therefrom the forces (F) and/or torques (M) acting between the two fastening elements (11, 12).
