Abstract

The role of hierarchy in gecko-like adhesive surfaces is presented. Experiments on two-level structured surfaces with micropillars of different dimensions demonstrate that hierarchy does not seem to positively influence adhesion of structured surfaces to planar substrates, but may be relevant when stiff materials or rough substrates come into play, where adaptability of the adhesive structure is required for successful contact.
