The model also showed that geckos are able to balance out the force of gravity by applying their own force to a wall; they can press and slide their feet toward their body and drag their feet across surfaces without falling. Gecko toes are well-studied and their sticky properties have inspired some incredible technology, such as stitch-free ways to seal wounds and sticky handheld paddles that may help soldiers scale walls someday. On April 9 and 15, 2021, the robotic gecko gripper - inspired by the sticky feet of a gecko - was tested on the International Space Station (ISS) by NASA astronaut Kate Rubins, Ph.D. with the .

In an episode of The Tyra Banks Show, she asked Quentin Tarantino about his foot fetish. graduates, many of whom have gone on to earn national recognition. Scientists have recreated geckolike adhesion using silicones, plastics, carbon nanotubes, and other materialsbut they've run into a scaling problem: The stickiness diminishes when the size of the adhesive exceeds a few square centimeters, severely limiting its practical applications. While not a professionally trained martial artist, she pursued ballet professionally and landed a spot at Londons Royal Academy of Dance.

More than a decade of research and engineering has culminated in gecko tape: a re-useable adhesive that has a structured surface similar to that of geckos and that outperforms the usual sticky tape. They get this seeming superpower from millions of microscopic, hairlike structures on their toes. Greaney and a team of researchers created a mathematical model that shows how the setae angle and the forces that act on a gecko as it climbs interact to create a delicate but powerful sticking system. When does spring start? This allowed the assembled patch to offer similar adhesive strength for sizes from a square millimeter to a human hand. When a gecko jumps to another surface or quickly changes direction to escape a predator, its toe hairs must absorb huge amounts of energy and redirect it. Its feet are so sticky that it could hang from smooth glass by one toe. The NIST synchrotron microscope that the researchers used to analyze the setae is unique in its ability to identify molecules on the surface of a three-dimensional object, measure their orientation and map their position. The gray squiggles represent lipid molecules. "It's this incredible synergy of the flexibility, angle and extensibility of the hairs that makes it possible.".
