A simple cotton T-shirt has been transformed into a source of electrical power, giving hope that one day people can charge from using the very clothes we're wearing, by a professor of mechanical engineering at the university of South Carolina in the US.
As the result a normal cotton T-shirt in a fluoride solution, dried it and baked it in an oxygen-free oven at a high temperature. So, the fibers on the surface of the T-shirt were transformed into a highly porous and absorptive form of carbon. T-shirt could be folded without breaking yet was capable of storing electrical storage capacity of the T-shirt and making it a more efficient super-capacitor, so that after thousands of charge - discharge cycles, performance did't diminish more than five percent. They believes that one day technology could be used to charge smartphones and other portable devies.
