[0067] The preparation method of the conductive rubber material described in the embodiment of the present invention adopts electron beam or γ-ray radiation for cross-linking, and the degree of cross-linking of the rubber can be regulated arbitrarily by controlling the absorbed dose, and the electron beam or γ-ray can penetrate the rubber glue layer , so that the overall cross-linking degree of the rubber is consistent and uniform; when the rubber conductive material is used as the sensor sensitive unit material, the consistency of the distribution of the resistance value of the strain sensor can be achieved, especially the change of electrical signals such as resistance and capacitance under the action of external force Sensitivity, stability, recovery and other properties. In addition, the method of the embodiment of the present invention is simple and controllable, and is easy to realize industrialization.
