Gecko adhesion

Submitted by jmalloldiaz on Fri, 12/07/2018 - 09:06

Geckos are able to adhere to surfaces thanks to a combination of their physical structures and behaviors. The fingertips of a gecko's hand are made up of lamellae, which are modified scales that contain special hairs called setae. These hairs are tiny, which allow for making better contact with surfaces via Van der Waals forces. As well, geckos have tendons in their hands that allow them to "peel off" their fingers when climbing, and their motions follow a complex set of behaviors that maximize their grip to surfaces.
