Large patches of an extremely strong new adhesive, inspired by geckos, can be used over and over again. For years scientists have tried to make strong, reusable adhesives by mimicking the microscopic hair-like structures on gecko toes that give the lizard its climbing ability. But those structures are hard to make, limiting the adhesives' size to a few centimeters. Now researchers from the University of Massachusetts, Amherst, have come up with a different gecko-inspired structure that works even better. They have created a reusable adhesive fabric that can be easily and cheaply made tens of centimeters wide and is three times stronger than gecko feet.
