The gecko adhesive system has attracted significant attention since the discovery that van der Waals interactions, which are always present between surfaces, are predominantly responsible for their adhesion. The unique anisotropic frictional–adhesive capabilities of the gecko adhesive system originate from complex hierarchical structures and just as importantly, the anisotropic articulation of the...
Nature has proven to be a tremendous resource in the development of new technologies with exceptional properties. With inspiration taken from the Tokay gecko, N. S. Pesika and co‐workers create a bidirectional switchable dry adhesive with properties reminiscent of the natural gecko adhesive pad. On page 574 the researchers demonstrate how their design opens the way for new gecko‐like adhesive surfaces...
