Metin Sitti's Research to Replicate Geckos' Ability to Keep Webbed Feet Sticky and Clean

"We are very close to commercializing the gecko-inspired synthetic adhesives for use in many industry sectors," says Professor Metin Sitti.

Sitti's paper, Staying Sticky: contact self-cleaning of gecko-inspired adhesives, published today in the Journal of Royal Society's, 'Interface Focus' publication (a cross-disciplinary themed publication promoting research at the interface between physical and life sciences), explains how the team performed experiments using three different sizes of mushroom-shaped elastomer microfibers and five different sizes of spherical silica contaminants to develop a fully-contaminated synthetic gecko-adhesive that could recover lost stickiness and lost adhesion at a rate comparable with that of the gecko.

Professor Sitti says this gecko-inspired synthetic adhesive could have implications for the defense, consumer products, sports, automotive, medicine, aerospace and robotics industries.
