Abstract Flexible strain sensors are promising candidates for intelligent wearable devices. Among previous studies, although crack-based have attracted a lot of attention due to their ultrahigh sensitivity, large usually causes fractures in the conductive paths. Because unstable crack structure, tradeoff between sensitivity and workable range is still challenge. As carbon nanotubes (CNTs) silver nanowires (AgNWs) can form strong interface with thermoplastic substrate strengthen network by...
