To release its foot, which might otherwise stay stuck, the gecko changes the angle of the setae, interrupting those forces and allowing the animal to take its next step. The National Science Foundation takes these ideas so seriously that it gave a $400,000 grant to scientists at the University of Akron and Rensselaer Polytechnic Institute to try making imitation gecko feet. The secret to that directionality was theangle and shape of the fabricated half-cylinder fibers in the silicon-based adhesive.
