British scientists have created a plastic that can store and release electricity, revolutionising the way we use phones, drive cars and even wear clothes.
It means the cases of mobiles and iPods could soon double up as their power source — leading to gadgets as thin as credit cards.
The technology could also lead to flexible computer screens that can be folded up and carried around like a piece of paper.
And it could even be used to create ‘electric clothes’ that charge up as a person moves around and which slowly release heat when the weather gets cold.
A prototype designed by the Imperial College London takes five seconds to charge from a normal power supply and can light an LED for 20 minutes.
