Latest Synthetic setae Stories
The uncanny ability of geckos to adhere to nearly any surface and even walk on ceilings is the result of a biological mechanism in their toes that the lizards can instantly turn on or off, according to new research appearing in the latest edition of the Journal of Applied Physics.
Inspired by the gecko’s ability to climb any surface, DARPA has manufactured a device to allow humans to also scale glass.
The University of Massachusetts Amherst scientists behind a super-adhesive material inspired by gecko feet have described a new, more versatile version of their invention that can be used on real-world surfaces.
People have always been looking to nature for inspiration for everything from art to medicine. And in a new study by University of Akron researchers, the affable gecko could lead to a new kind of adhesive tape.
Human adhesives are famed for their fallibility. Gooey glues soon lose their grip, are easily contaminated and leave residues behind. But not gecko feet. Geckos can cling on repeatedly to the smoothest surfaces thanks to the self-cleaning microscopic spatula-shaped hairs (setae) that coat the soles of their feet.
The science behind gecko toes holds the answer to a dry adhesive that provides an ideal grip for robot feet. Stanford mechanical engineer Mark Cutkosky is using the new material, based on the structure of a gecko foot, to keep his robots climbing.
Researchers move one step closer to nature with the development of polymers and directional adhesion that follow the workings of a gecko's foot.
Renowned for their ability to walk up walls like miniature Spider-Men--or even to hang from the ceiling by one toe--the colorful lizards of the gecko family owe their wall-crawling prowess to their remarkable footpads. Each five-toed foot is covered with microscopic elastic hairs called setae, which are themselves split at the ends to form a forest of nanoscale fibers known as spatulas. So when a gecko steps on almost anything, these nano-hairs make such extremely close contact with the...
