Recently, we have seen developments in generating renewable energy from sources as diverse as bubble wrap and by-products from steel production. Now, an international research team led by scientists at the University of Texas (UT) at Dallas and Hanyang University in South Korea has developed a high-tech yarn, dubbed Twistron, that can generate electricity when stretched or twisted. The yarn is made from carbon nanotubules – hollow cylinders of carbon with a diameter 10,000 times smaller than a human hair. The nanotubules are twist-spun into high-strength, lightweight yarns. In order for the yarn to generate electricity, it must first be…
