A conducting wire that can be stretched to 14 times its original length has been developed by scientists at the University of Texas at Dallas, US. They say it could find use in flexible electronics devices and artificial muscles, as well as other devices such as giant deformation strain sensors.
Ray Baughman and colleagues fabricated super-elastic, conducting fibres by wrapping carbon nanotube sheets oriented in the fibre direction on to a stretched rubber fibre core of styrene-(ethylene-butylene)-styrene (SEBS) copolymer.
