PIEZOELECTRIC FORCE MEASUREMENT DEVICE

摘要

The invention relates to a force measurement device comprising - a deformation body (10) supported on a base, which is in a zero position (12) when unaffected by external forces (13) and which can be deflected by an external force (13), and - a sensor (30) which comprises a piezo element and by means of which a signal dependent on the deformation of the deformation body (10) can be generated and transmitted to a control apparatus, wherein a measured value representative of the external force (13) can be determined by the control apparatus. The invention is characterized in that an actuator (31) which comprises a piezo element can be actuated by the control apparatus dependent on the sensor signal so that a restoring force can be exerted against the external force (13) on the deformation body (10), which can be thus transitioned back to the zero position (12) thereof.
