geckos defy gravity
2014-08-13 05:18:11

redOrbit Staff & Wire Reports - Your Universe Online 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. Geckos, along with spiders and some insects, appear to defy gravity with the way they are able to scale walls and cling to high surfaces, the Oregon...

gecko-inspired human climbing mechanism
2014-06-06 11:55:22

Gerard LeBlond for redOrbit.com - Your Universe Online The gecko is a small lizard that can climb on a variety of surfaces, including glass. It uses adhesive pressure equaling 15 to 30 pounds per square inch (PSI) on each limb. Theoretically, the gecko can also support its body weight hanging on one toe. Each toe is comprised of a microscopic hierarchical structure which are little stalk-like extensions 100 microns long and 2 microns around. Each stalk is a bundle of hundreds of tips...

Gecko-Inspired Adhesive Material Now Usable On Wood, Other Surfaces
2014-04-20 06:48:37

redOrbit Staff & Wire Reports - Your Universe Online 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. The improved version of the reusable material known as Geckskin is capable of strongly adhering to a greater variety of surfaces. However, just like a gecko’s feet, it is able to detach from those surfaces easily, the...

Gecko Grips Just As Good In Wet Habitats As In Dry Ones
2013-04-02 10:44:07

Brett Smith for redOrbit.com - Your Universe Online 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. According to the study, which appeared in the Proceedings of the National Academy of Sciences (PNAS), geckos can cling to wet hydrophobic surfaces like plant leaves and stems just as well as they can to dry surfaces. However,...

Humidity softens setae to tighten gecko's gripHuman 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. Back in 2002, Kellar Autumn found that these dry hairs are in such intimate contact with surfaces that the reptiles 'glue' themselves on...

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. A Stanford mechanical engineer is using the biology of a gecko's sticky foot to create a robot that climbs. In the same way the small reptile can scale a wall of slick glass, the Stickybot can climb smooth surfaces with feet modeled on the intricate...

Researchers move one step closer to nature with the development of polymers and directional adhesion that follow the workings of a gecko's foot Nanotechnology has not only brought nature and engineering closer together; it has encouraged collaboration among researchers of different disciplines. In one such collaboration, two researchers drew on the extraordinary stickiness of a gecko's foot to develop a synthetic adhesive to help robots scale walls. NSF-funded researchers Mark Cutkosky, an...

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...
