providing a single-layered or multi-layered substrate with a first surface and a second surface;

providing one or more sensor films which each comprise at least one sensor area and have a first surface and a second surface facing away from the first surface;

applying one or more functional elements to the first surface of one or more of the one or more sensor films to form a shape on the first surface of the one or more of the one or more sensor films, the one or more functional elements performing an electrical and/or optical function;

applying the one or more sensor films with the one or more functional elements to the second surface of the substrate such that the first surface of the respective sensor film rests on the second surface of the substrate at least in areas;

thermoforming a series of layers comprising the substrate and the one or more sensor films applied to the second surface of the substrate such that, during the thermoforming, on the first surface of the substrate a surface relief is formed which is determined by the shape on the first surface of the one or more of the one or more sensor films,

wherein variable method parameters of the thermoforming process are predetermined such that the softening or plasticization of the substrate occurs at lower temperatures and/or pressures than the softening or plasticization of the one or more sensor films, and

wherein the one or more sensor films have, in each case in the at least one sensor area, one or more capacitive and/or resistive sensor elements, and the one or more sensor films in each case have at least one connection area and/or contact area for the contacting of one or more of the sensor elements, and

wherein one or more plastic labels are applied as one or more elements to a first surface of a base film of the sensor film, and

wherein the one or more plastic labels are applied to the base film in the sensor area of the sensor film and completely or partially overlap the sensor area.
