U.S. scientists have developed a micro-fiber capable of producing enough electricity to charge an MP3 player or mobile phone.
Electricity production comes from the movement of the fabric (like a T-shirt) while traveling or when the wind blows.
During a movement, there is friction of the fibers (composed of nano-son gold and zinc oxide) thus producing an electric current.
According to scientists, one square meter of fabric made this micro-fiber could produce 80 mW, which they believe would be sufficient to charge a small battery ...
Of course, there's a catch (as always), the properties of zinc oxide will deteriorate in the presence of moisture. Not very practical, especially in the winter! Anyway this is an application of nanotechnology more.
