Geckos have developed foot pads that allow them to maintain their unique climbing ability
despite vast differences of surfaces and environments, from dry desert to humid rainforest.
Likewise, successful gecko-inspired mimics should exhibit adhesive and frictional
performance across a similarly diverse range of climates. In this work, we focus on the effect
of relative humidity (RH) on the “frictional-adhesion” behavior of gecko-inspired adhesive
pads. A surface forces apparatus was used to quantitatively measure adhesion and friction …
