Gecko-inspired reversible adhesive materials with unprecedented force capacities are described by D. Irschick, A. Crosby, and co-workers on page 1078. A simple scaling parameter, which describes both natural and synthetic reversible adhesive systems, leads to the development of unpatterned synthetic adhesive materials. Adhesive force capacities as high as 2950 N are achieved, not with fibrillar features, but through an integrated design with inextensible, draping fabrics, inspired by the skin-tendon morphologies found in the tokay gecko. The image presents an arm of a tokay gecko in front of a draping fabric.
