  • Device having a structured coating for adhering to other surfaces
    Patent number: 11583381
    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.

  • ADHESIVE SYSTEM FOR ROUGH SURFACES
    Publication number: 20220387160
    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 one stem 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 lower modulus of elasticity and is in the form of a film that interconnects the protrusions. The film can also be in the form of a removable film.
