Nanofibres made that produce power when rubbed together.

Mobile phone battery running out mid-conversation? One day you mightbe able to make a few vigorous arm movements while wearing a nanowireelectricity-generating shirt to keep the battery going.

Thisis power-dressing in the real sense: nothing to do with shoulder padsor 1980s office dramas. Zhong Lin Wang and his colleagues at theGeorgia Institute of Technology in Atlanta have made a yarn out ofnanofibres that produce charge when they are rubbed against oneanother. Materials woven from these yarns could be used forself-powering clothes, shoes or biological implants such as pacemakers.The work is published in Nature
