Physicists from the United States created the «eternal» anti-glare coating for the screens of mobile phones and any other gadgets that runs on the same principles, which are arranged in the eyes of ordinary moths, according to an article published in the journal Optica.

«Our flexible film can be installed on smartphones or tablets that will be making their screens are bright and clear even in bright sunlight on the street. Besides the fact that they almost do not reflect light, our films besides protected from scratches and can self-clean, which will save the screens of phones from accumulating on the dust and traces of greasy fingers,» says Shin-PSC (Shin-Tson Wu) from the University of Central Florida in Orlando (USA).

Recent years physicists, chemists and engineers are actively investigating a device separate organs and bodies of living organisms, trying to use «inventions of evolution» in new technologies and devices.

Thus, the American physicists have created a «perfect» medical needle and the patch, after examining the device, needles of a porcupine and nipples parasitic worms, and their canadian counterpart increased the strength of the glass is 200 times using the secrets of the shells. Robots, imitating manner of movement or «thinking» animals, has reached record speeds, and the wings of butterflies helped British scientists double the efficiency of solar cells doubled.

And his colleagues have added to the number of such natural know-how of the eyes of moths, which, as it turns out, can be used to create transparencies, absolutely does not reflect light and it does not interfere with the operation of the touch screen.

How to tell the authors, moths and many other insects with large facette eyes, face almost the same problem that the owners of smartphones. The glare prevented them from seeing in the dark, and the light reflected from the surface of the eye in the daytime helps predators find these butterflies, usually merging with the bark of trees or other objects.

Physics several decades ago found that in reality this is not happening – the eyes of the moth are arranged in such a way that they almost do not reflect light and prevent reflections appearing on its surface. Enough scientists have been trying to copy their structure, but it’s not been done to date due to the sophisticated eyes of a moth.

The team Have managed to solve this problem through technology «self-Assembly» of nanoparticles capable without the intervention of man to unite in patterns similar to what looks like the surface of the eye moth. This allows to produce film with such nanoparticles in the automatic mode, not to build them manually, as it was trying to do other physics.

As shown by the first field test of this film, it is about four times increases the contrast of images on the screen of a smartphone while on a brightly lit street, and 10 times – indoors or in the shade. Now scientists are working on improving the mechanical properties of this film in order to make it more suitable for use in «field» conditions. In addition to anti-reflective coatings, these films can be used to improve the efficiency of solar cells that will absorb them blagodarya more light than usual.
