- Abstract
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.
