Tactile sensor is the key link for intelligent robot to perceive the external environment and interact with people.Multiple physi-cal measurements and high ductility make tactile sensors more widely used.A flexible tactile sensor with simple manufacturing process and low costs is presented.Based on the change of resistance,it can detect temperature and contact pressure.A sandwich structure of the sen-sor composed of PDMS film,paper-based silver nanowires and PDMS film is designed.A 3×3 array of paper-based silver nanowires is pro-cessed,and copper wires are led out at the end of the array with conductive silver paste.The size of the whole sensor is 3 cm×3 cm.Dur-ing the experiments,the resistances at the array intersection are measured when applying pressure and changing surface temperature.Re-sults show that the pressure detection sensitivity of the sensor is 2.8 Ω/N and the temperature detection sensitivity is 0.18 Ω/℃.The structure and preparation process of sensor here are simple and feasible,holding broad promise in electronic skin of robots.
