Abstract (en)

[origin: CA3174343A1] The invention relates to a moulded body comprising a structured surface, wherein the surface has a structuring including a plurality of protrusions (pillars), at least each having a stem and comprising an end face pointing away from the surface. With this end face, the protrusions come into contact with the surface of the adhered object, wherein at least one protrusion comprises at least one structural feature, which, when loading the protrusion, leads to a directed deformation of the protrusion by changing the adhesion.
