People will crawl on the wall

Stepping on the wall will soon become a reality thanks to very high adhesion of gloves and shoes, US scientists claim.

Techniques to help cows get on the wall simulate gecko activity.

Gecko toes have many rows of parallel scales. Under the microscope we can see that the top of each scale has a lot of tiny hairs (about 5,000 fibers per mm ² ). Taking into account that each gecko foot has about 500,000 hairs, each fiber has twice the length of human hair width. When the gecko stretches the toes down, the hairs also stretch and lean backwards. Thanks to that clever manipulation, many hairs come into contact with the plane.

Telegraph said , during the past decades, the world of science has found ways to make fabrics with the ability to stick like gecko feet. Stanford University scientists in the United States created such a fabric . Their fabric has a rubber-like texture and its surface is covered by several thousand tiny hair-like polymer fibers at the gecko's feet. These strands are tens of times thinner than human hair. New fabrics are very strong and can be recycled. It has been tested on a gecko-like robot. Tests show that geckos can move on vertical walls of glass and metal.

From 2006 until now, Stanford University's expert team continued to upgrade super-adhesive fabrics so that it could withstand human weight.

Professor Mark Cutkosky, the lead researcher, said that the interesting point of gecko toes is the ability to stick one way . When the gecko moves its foot in the other direction, the sticky phenomenon disappears. Gecko toes are completely different from sticky tape. If we swipe the tape in one direction, we will have to peel it in the opposite direction. But if geckos push their feet forward to grip, they just need to push in another direction to lift.

' We can also take a step on the cement floor with gum in the bottom of the shoe to illustrate. After pressing your foot on the floor, you must lift your leg to pull the shoe up. But with the material sticking in the direction, you just need to shift the foot in a different direction to bring the shoe up, 'Cutkosky added.
