Highly stretchable, conductive, and sensitive strain-sensing materials have aroused wide interest owing to their potential in wearable devices. A facile and scalable method to fabricate a carbon-nanotube- (CNT-) bridged silver nanoparticles (AgNPs) strain sensor based on thermoplastic polyurethane electrospun membrane (TPUEM), which exhibits a large strain range with a high gauge factor simultaneously, is demonstrated. It exhibits a high stretchability with large workable strain range of up to 550%, high gauge factor of 7066, good durability over 1000 cycles, and comparable stability under various strains. Importantly, it can be used for human motion detection, including subtle movements and large-scale human motion, showing its promising application in flexible and wearable devices.
