Using a simple layer-by-layer coating technique, researchers have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities — and the best performance so far in a textile-based supercapacitor.
