Someday, your shirt might be able to power your iPod ? just by doing the normal stuff expected of a shirt.
Scientists have developed a way to generate electricity by jostling fabric with unbelievably tiny wires woven inside, raising the prospect of textiles that produce power simply by being stretched, rustled or ruffled by a breeze.
The research, described in Thursday’s edition of the journal Nature, combines the precision of ultra-small nanotechnology with the elegant principle known as the piezoelectric effect, in which electricity is generated when pressure is applied to certain materials.
While the piezoelectric effect has been understood at least as far back as the 19th century, it is getting creative new looks now, as concerns about energy supplies are inspiring quests for alternative power sources.
