Researchers at the University of Texas and Mechanical University in South Korea have developed a high - tech yarn that generates electricity when stretched or stretched . The yarn is made from carbon nanotubes , which are hollow strands of carbon , 10,000 times smaller in diameter than a human hair . The fibers can be used to harvest energy from the motion of ocean waves , among other applications .
Researchers at the University of Texas and Hanyang University in South Korea have developed a high-tech yarn that generates electricity when twisted or stretched. The yarn is made from carbon nanotubes, which are hollow cylinders of carbon, 10,000 times smaller in diameter than a human hair. The technology could be used to harvest energy from the motion of ocean waves, among other applications.
