Abstract

A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.
