New fabric can generate electricity
We’re constantly looking for innovative ways to improve the Springwise experience, and so we’re now introducing BeeLine Reader, a new technology that helps you read more quickly and efficiently. To learn more about BeeLine Reader, an award-winning startup funded by Intel Capital, see BeeLineReader.com.
We have previously seen materials that provide power in unusual ways, including a fabric that can harvest energy from wind and a fuel cell powered by sweat. Now, researchers at Chalmers University of Technology, in Sweden, have developed a woven fabric that generates electricity when it is stretched or exposed to pressure. Chalmers researchers, Anja Lund and Christian Müller, created the material by weaving a piezoelectric yarn together with an electrically conducting yarn. The resulting fabric can generate enough energy to light an LED. Additionally, it can also send wireless signals or power a pocket calculator or digital watch.
