In the study published in Nano Energy ("Flexible, durable, and washable triboelectric yarn and embroidery for self-powered sensing and human-machine interaction"), researchers tested multiple designs for power-generating yarns. To make them durable enough to withstand the tension and bending of the embroidery stitching process, they ultimately used five commercially available copper wires, which had a thin polyurethane coating, together. Then, they stitched them onto cotton fabric with another material called PTFE.
