Abstract In this study, a strain sensor via two-component polyurethane was introduced. The sensor has a laminated structure composed of an amino functional silane KH-550/short-hydroxyl multi-wall carbon nanotube (SHMWCNTs) layer and a graphene nanoplates (GNs)/silver nanoparticles(Ag)/silicone rubber (SR) layer. The hydrogen bonding between layers imparted high tensile strength (650%), wide linear sensing region (0–400%), high linearity, high response rate, low detection limit (0.5%) and long-term durability to the proposed resistive strain sensor. The strain sensor was affixed to data bands and a data glove for monitoring human body motions, including finger joint, knee joint, and calf movements. Furthermore, the gait detection was performed. Owing to the advantages of the laminated strain sensor, namely, its simple preparation process and excellent electrical properties, new avenues are expected to be opened for research on strain sensors in wearable and flexible electronics.
