Abstract:
Geckos can adhere upside down on a horizontal surface and yet can climb rapidly on most vertical walls. This feat is accomplished using a hierarchical fibrillar interface. This paper reviews design principles of synthetic fibrillar interfaces that mimic surface structures in lizards and insects designed for enhanced contact and adhesion. In addition, we will address the role that statistics plays in quantifying fibrillar adhesion.Keywords: ADHESION; LOCAL LOAD SHARING; GLOBAL LOAD SHARING; COMPLIANCE; BUCKLING; STATISTICS OF PILLAR BUNDLES
