Abstract: A fabricated microstructure (10) comprising at least one protrusion (18) capable of providing an adhesive force at a surface of between about 60 and 2000 nano-Newtons. A stalk (12) supports the protrusion (18) at an oblique angle relative to a supporting surface. The microstructure can adhere to different surfaces.

Abstract: A method of forming an adhesive force includes removing a seta from a living specimen, attaching the seta to a substrate, and applying the seta to a surface so as to establish an adhesive force between the substrate and the surface. The seta is applied to the surface with a force perpendicular to the surface. The seta is then pulled with a force parallel to the surface so as to preload the adhesive force of the seta.
