An international team of nano-materials researchers from the University of Illinois at Chicago and Korea University have produced an ultrathin film that is both transparent and highly conductive to electric current. The film, actually a mat of tangled nanofiber, electroplated to form a "self-junctioned copper nano-chicken wire," is also bendable and stretchable, offering potential applications in roll-up touch screen displays, wearable electronics, flexible solar cells and electronic skin.
