Abstract 

    The mechanisms of adhesion in climbing animals have many properties that are the envy of engineers, and therefore have enormous biomimetic potential.  These include (a) good adhesion on many substrates (including wet ones), (b) reversible adhesion and re-usability, (c) self-cleaning and (d) only sticking when required. Such research lies on the border between biology and materials science. In this talk, I will describe how a variety of approaches provide insights into how tree frogs adhere so well to overhanging surfaces, and the morphology and physical properties of their toe pads, research which underlies the fabrication of toe pad mimics.

About the lecturer

     Prof. Jon Barnes is now an Honorary Research Fellow of the Centre for Cell Engineering, Glasgow University. With a deep background in invertebrate neuroscience, for the last 15 years he has devoted himself to the research of adhesion and friction in tree frogs and their implications for biomimetics, a much productive research area. He has published over 100 articles including an invited review in Science discussing the biomimetic solutions to sticky problems, and contributed chapters for two books. He was once the volume editor of Journal of Comparative Physiology A and section editor for the “Biomimetics – Animals”  section of Encyclopedia of Nanotechnology.
