Zhong Lin Wang at the Georgia Institute of Technology in Atlanta, Xing Fan at Chongqing University in China and their co-workers wove a fabric (pictured) using wool fibres and two types of polymer wire: a photovoltaic one and another that collects mechanical energy. The 320-micrometre-thick flexible fabric converted energy from both sunlight and movement, making enough electricity to charge a mobile phone or power a wristwatch.

Along with exploiting solar power, such a device could harvest energy from the motion of walking, the wind blowing or a moving car.
