Project:

Biologically-inspired attachment systems. Experimental studies on natural attachment devices in flies, beetles, geckos (upper figure) aid in understanding functional principles. We apply approaches of contact mechanics for description of behaviour of biological systems on global (the entire attachment pad) and local (single seta or spatula) scales. Computer modelling is used to simulate adaptability of hairy attachment systems with different levels of hierarchy on surfaces with different surface profiles (middle picture). Moulding technique (lower picture) is used for design of surfaces with structures similar to the biological attachment devices, in order to prove our working hypotheses and to find a way for designing bionic (biomimetic) industrial applications.

Other interests: tribology, contact mechanics, surface characterization
