Abstract

The invention relates to a device for detecting a force and/or a torque, said device comprising an elastic element that can be deformed by the action of a force and/or a torque and surrounds an inner region, and a sensor for detecting a deformation of the element, caused by the force or the torque, forming electrical signals. The sensor is arranged in the inner region of the elastic element. The elastic element comprises at least one electroconductive structure which at least partially shields the sensor from electrical fields emanating from the region around the elastic element.
