T-shirts developed that could charge mobile phones The researchers turned the t-shirt fabric into a 'supercapacitor'
Scientists at the University of South Carolina have found a way to use a cheap T-shirt to store electrical power.
It could pave the way for clothes that are able to charge phones and other devices.
Experts predict that new technologies including roll-up smartphones and laptops will be on the market soon.
These developments would spur on the need for "flexible energy storage", said the professor behind the project.
Xiaodong Li, a professor of mechanical engineering at the university teamed up with post-doctorate researcher Lihong Bao to find a solution.
The pair wrote up their findings for the Advanced Materials journal.
They used a T-shirt bought from a local discount store, which was soaked in a solution of fluoride, dried and then baked in an oxygen-free environment at high temperature

Professor Hubler, who runs a research and development group at the Chemnitz University in Germany, has developed new inks that make it possible to produce flat speakers or printed solar cells. To produce a loudspeaker, the ink is printed on a sheet of paper and contains multiple layers of conductive organic polymer and a piezoelectric layer. Applying an electric current makes the layered ink vibrate, with the end result being a sheet of paper that is capable of producing quite loud and clear sound.
