The object of the invention of developing a three-dimensional flexible registering unit which can measure mechanical operations in the region at any desired positions over a defined length is achieved by virtue of the fact that said registering unit is in the form of a cable and comprises, in the three-dimensional extent, a flexible protective sleeve and two coaxially arranged conductor tracks, wherein one conductor track surrounds the other conductor track, and one of the conductor tracks is used as a measuring electrode and the other conductor track is in the form of an electrical resistor and has a voltage gradient, and a dielectric which electrically separates the two conductor tracks from one another in the quiescent state and enables punctiform or areal contact between the two conductor tracks when a mechanical force acts from the outside is situated between the two conductor tracks, and a measured value recording and evaluation unit which is suitable for determining a change in voltage or resistance triggered by operating the registering unit with a contact-pressure force vector is provided.
