Researchers at NC State have developed a way to print liquid metals into 3D structures at room temperature. The structures are stabilized by a thin oxide 'skin' that forms on the liquid metal. The approaches shown here represent new ways to direct write metals in 3D. In addition, the resulting components can, in principle, self-heal ( "Self-healing stretchable wires" http://www.youtube.com/watch?v=lfAOEt...) and be ultra-stretchable ( "Ultra-stretchable wires" http://www.youtube.com/watch?v=QlVuIK...).
