#Researchers invent super-elastic conducting fibers to make artificial muscles, sensors, and capacitors A University of Texas at Dallas research team has made electrically conducting fibers that can be stretched reversibly to more than 14 times their initial length and
whose electrical conductivity increases 200-fold when stretched. The research team is using the new fibers to make artificial muscles,
as well as capacitors with energy storage capacity that increases about tenfold when the fibers are stretched. Fibers and cables derived from the invention might one day be used as interconnects for super-elastic electronic circuits

the scientists describe how they constructed the fibers by wrapping lighter-than-air, electrically conductive sheets of tiny carbon nanotubes to form a jellyroll-like sheath around a long rubber core.
The new fibers differ from conventional materials in several ways. For example, when conventional fibers are stretched,
the resulting increase in length and decrease in cross-sectional area restricts the flow of electrons through the material.
But even a iantstretch of the new conducting sheath-core fibers causes little change in their electrical resistance, said Dr. Ray Baughman,
senior author of the paper and director of the Alan G. Macdiarmid Nanotech Institute at UT Dallas. One key to the performance of the new conducting elastic fibers is the introduction of buckling into the carbon nanotube

said the structure of the sheath-core fibers"has further interesting and important complexity.""Buckles form not only along the fiber's length,
