There is no denying it, a lot of innovation is taking place in the field of smart textiles. That is why we were super excited to read, in an issue of Science, that a research team,led by scientists at The University of Texas at Dallas and Hanyang University in Seoul, South Korea, have developed a new form of yarnology, called Twistron, that generates electricity when stretched or twisted.
According to the University of Texas at Dallas news centre article, No Batteries Required: Energy-Harvesting Yarns Generate Electricity, the yarns are constructed from carbon nanotubes, that are hollow cylinders of carbon 10,000 times smaller in diameter than a strand of human hair. They article explains, “The researchers first twist-spun the nanotubes into high-strength, lightweight yarns. To make the yarns highly elastic, they introduced so much twist that the yarns coiled like an over-twisted rubber band. In order to generate electricity, the yarns must be either submerged in or coated with an ionically conducting material, or electrolyte, which can be as simple as a mixture of ordinary table salt and water.”
