The team of researchers, led by Radislav Potiraylo from the center of global research at GE (General Electric) published the article in the Nature Photonics about creation a fundamentally new type of ultra-sensitive sensors, based on nanotubes of carbon. It is reported, that physicists assembled the idea of ​​a new highly sensitive thermal radiation detector based on the study of the surface structure of the wings of Morpho butterflies. The fact, that the color of the Morpho butterfly wings change its color under the influence of the slightest changes in environmental temperature and color change is not determined by the presence of pigments, as is in the case of most animals, - the color of the wings of butterflies changed under the influence of structure of smallest chitin layers on the surface of these wings, which refract by the specific way the light, falling on them, acting as miniature prisms. The chitinous layers on the surface of the wings of butterflies change their structure due to changes in ambient temperature in the ten-thoUSAndths of a degree. The scientists used a chitinous layers of the wings Morpho butterflies and built a miniature heat-sensitive sensor, connecting them with a thin carbon nanotubes. This sensor can operate over a wide temperature range and is able to record temperature changes of up to 30 per second. The invention may interested in military labs, that can use this sensor for installation on air defense missiles, which can detect stealth warplanes, which are invisible for usual air-defense radars.
