Researchers from Cornell University in New York, have developed a device enabling a man to walk on the walls. Palm-sized device, is inspired by the construction of the legs Florida resident. At the terminals of the legs has a drop of oil secreting glands, and move on to the stems and leaves him there to the surface tension between oil molecules and the surface.
Professor Paul Steen from Cornell University in the United States constructed a device in which a similar effect occurs with the participation of water molecules. Filling the tiny holes the size of droplets in a flat tin causes the "glue" it to the surface. The process of pumping water molecules may be there in two directions, is regulated by an electric field, so it is possible to control the device, the glue and peel off blade at any time. One molecule of water is not such a powerful effect as a larger quantity. Professor Steen has observed that the more particles are pr at any given time, the more clout associated with the surface. By reducing the diameter of orifices and the size of water droplets, increasing the force of surface tension, making weight, we want to stick may be higher. Prof. Stone believes that the drilled holes with a diameter 1,000 times smaller than a human hair, on the surface of lamellae with a width of 7.5 cm, to preserve the body, weighing about 130kg. Prof. Stone and his colleagues have developed a device model that can allow a man to walk on vertical wall. Plaques could be an element of dress, overalls, which would allow attachment of the free and the disconnection of hands and feet during movement. Previous tests have shown that using only battery power 9woltowej, pumped water droplets produce surface tension to allow the insertion of such surfaces as wood, plastic, glass, metal, brick, and even sandpaper. The invention is so promising that further research into co-financing has made the government agency DARPA (Defense Advanced Research Projects Agency), which is responsible for seeking and implementing new technologies in the U.S. Army. These innovative "suckers" can have wide application both in military operations, or rescue, but also in many other professions. The requirements of this device are very small, just a simple battery and water, so the production will be relatively cheap and accessible to all.
