英文摘要	Stretchable strain sensor, as a crucial component in wearable intelligent devices, becomes one of the recent research hotspots with promising potential in human-interactive, personal health monitoring, and flexible smartphone. Graphene-based materials have been reported for high-performance strain sensors. However, there still remained some limitations such as high production costs, low sensitivity and stretchability. Here, a highly stretchable and ultra-sensitive strain sensor based on nickel nanoparticles and graphene coated polyurethane sponge (Ni@GPUS) ternary hybrid material is reported. Thereinto, Ni@GPUS is fabricated via a series of technique including graphene-coated polyurethane sponge, electrodeposition of nickel nanoparticles and encapsulation by polydimethylsiloxane. The obtained sensors can be stretched up to 65% and exhibits remarkable gauge factor up to 3360.09. Furthermore, the fast signal response (<100 ms) and 1000 cycles of stretching and bending prove the quickly steady state response and long-term durability of the sensor. Besides, the mechanisms of the sensor are proposed. Moreover, the strain sensor is used as bodily motion sensors to monitor finger bending and facial muscle tension, showing great potential in fields of flexible, stretchable, and wearable electronics.
