A highly sensitive strain sensor based on a carbonized polyacrylonitrile nanofiber woven fabric

In this study, a flexible highly sensitive strain sensor was fabricated using thermoplastic polyurethane (TPU) and carbonized woven fabric based on polyacrylonitrile nanofiber yarn (PNY). The carbonized PNY fabric was prepared according to the following steps: filaments fabricated by electro spinnin...
