Abstract

A device and method for measuring at least one of a force component and a torque component. The device includes a deformation member, for measuring at least one of a force component and torque component, a separate measuring element, configured to measure at least one force component, and an electronics unit, connected to the measuring element configured to evaluate a measuring signal of the measuring element. The deformation member includes a base part and at least one tongue movable with respect to the base part. The base part is arranged so that a gap between the measuring element and the tongue has a gap width variable in response to the force component introduced onto the deformation member. The measuring element is configured to convert a change in the gap width into a measuring signal. The method includes the step of changing the gap width between the tongue and the measuring element by introducing the force component into the deformation member. The method further includes the step of detecting the change in the gap width by the measuring element. The method further includes the step of directing the measuring signal by the measuring element to the electronics unit for furt…
