The invention relates to an extensive sensor unit for force and/or pressure sensor systems, comprising first and second insulating carrier films (1, 2), which are arranged one over the other and bear first and second conducting track patterns (3, 4) on their surfaces that face one another, between which conducting track patterns elastically deformable first spacing elements (5, 6, 7) for elastically preloading the carrier films are arranged. At least one of the conducting track patterns is divided by the first spacing elements into a plurality of contact regions, in which contact between the first and second conducting track patterns can be established when force is applied to at least one of the films. The conducting track patterns are formed partially by resistive coatings having specified electrical sheet resistance and have terminals for connecting to an evaluation circuit, which outputs an output signal in accordance with the position of the resistance values produced by compression of the first spacing elements. A number of second spacing elements (7) is arranged on at least one of the conducting tracks facing each other, which second spacing elements are arranged at a distance from each other and have less mechanical resistance to compression than the first spacing elements.
