Abstract: A flexible resistive pressure sensor based on rGO/PDMS is introduced in this paper. And a new method for preparing flexible pressure sensors is proposed; the influence of graphene concentration on the sensitivity of the sensor is studied. The results show that the flexible pressure sensor has high sensitivity. When the graphene doping amount is 4wt%, the sensitivity reaches the maximum value of 76.321 kPa－1. It can be used to detect the degree of bending of human joints and the pulse movement in the wrist. The resistive flexible pressure sensor is expected to have broad application prospects in the field of robot skin and smart wear due to its low manufacturing cost, high sensitivity, and durability.
