Effect of Detachment Speed on Adhesion Strength of Gecko Inspired Adhesive Devices

Abstract

Gecko has a special micro hair on its foot to attach to a surface and climb walls. Mimicking its hair, easily detachable adhesive devices have been developed creating micro-structures on the surfaces. Adhesion strength of these devices changes with peeling direction. Therefore, this dependency enables a compatibility of strong adhesion and easy detachment. In this study, the effect of peeling speed on the adhesive strength of the devices is experimentally investigated.
