Solar powered cell phone

SOME time ago have found a voice conversion technique to electric power using the material "PIEZO-Electric". Imagine if this technology in mobile pinned, so that it can be said that mobile devices including self-powered devices. Research Cagin, professor of chemical engineering department at the University of Artie McFerrin A & M Texas, bringing 'PIEZO-electric' into nanoscale dimensions, which dramatically alter the performance characteristics. Very thin material that was very sensitive to pressure, such as vibrations caused by sound. PIEZO-electric was actually kind of crystal or ceramic which generate electricity if given a mechanical pressure. According to an article in 'Science Daily', it's the first thing was first discovered by scientists 1880an in France and has been applied in several applications. Materials 'PIEZO electric' has been widely used in electrical equipment such as a lighter and a microphone. A sensor such as microphone recorder can be used as an example. If one mic can generate a maximum of 100 MW and if we want a module that can generate 10 W peak voltage, it can take approximately 100 mic. Research Cagin successfully changed the ratio. In fact he managed to make the material 'PIEZO-electric' certain types of specific thickness mampumencapai level (about 21 nanometers, as a comparison with the thickness of human hair 100 thousand nanometers) So a component with a 'PIEZO-electric' optimal size can produce maximum power to run the phone in just a sound vibration. Cagin also supported by Zhong Lin Wang, a professor and nanotechnology researcher at Georgia Institute of Technology. Wang has melaklukan trials with a pair of fiber sheets coated zinc oxide nano wire. Knitted on a shirt, that fiberglass can use the movement of the user's body to provide power to portable devices. Wang said that if millions of these fiber pairs, each 1 cm long, have sewn on woven fabric covering 9 square feet (one size fits large) to be used to operate an iPod. Technologies that convert the vibrations in the form of this energy is not only suitable to be applied on the phone. Possibly, this technology can also be applied to a variety of devices and other mobile electronic sensors that require little power consumption. (various sources / nk)
