shape-shifting aircraft

Super-elastic carbon nanotube-based conducting fiber could be used to build shape-shifting aircraft

Scientists, working at the University of Texas at Dallas, have developed a special type of conducting fiber, whose electrical conductivity increases dramatically when stretched. Made from tiny sheets of carbon nanotubes (CNT), wound around a cylindrical rubber core, the ultra-elastic fiber can be stretched to around 14 times its original length, without losing any of…
