The Challenge

Adhesives are used in every industry and are a constant part of everyday life. However, traditional adhesives are single-use and often use a strong glue that can leave a sticky residue once removed.

Innovation Details

Geckskin™ is a technology, not a material. A Geckskin device can be made from an array of commercially available materials on commercial manufacturing equipment to address an application. Geckskin utilizes a phenomenon called ‘draping adhesion’, which mimics the skin-bone-tendon system of gecko feet to create a powerful adhesion device that leaves no residue. It is composed of two components, a soft elastomer and a stiff fabric. Together, the material can conform to a surface while maintaining high elastic stiffness.

Biomimicry Story

Geckos are renowned for their sticky feet that enable them to climb a variety of surfaces. However, the tendon and bone structures behind the feet are just as important, and they help to maximize the gecko’s ability to stick. In most animals, soft tendons directly connect bones to muscles. However, in geckos’ feet, the tendons are stiff and stretch from the bone to the skin- all the way to the underside of the feet. This helps to stiffen the feet and evenly distribute forces, making it easier for the gecko to stick.
