Nacre-inspired highly stretchable piezoresistive Cu-Ag nanowire/graphene synergistic conductive networks for strain sensors and beyond

Recently, it has become highly desirable but remains a challenge to design strain-sensing materials with rational geometric structures that endow the strain sensors with high sensitivity, large stretchability and a broad sensing range simultaneously. Herein, core-shell Cu-Ag nanowires (NWs) with tun...
