Abrégé

A method for producing a multilayer body and a multilayer body, wherein the method includes: providing a single-layered or multi-layered substrate with a first surface and a second surface, providing one or more sensor films which each have at least one sensor area and have a first surface and a second surface facing away from the first surface, applying the one or more sensor films 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 shaping, of one or more of the one or more sensor films.
