Abstract

The invention provides a conductive rubber material used for a flexible sensor as well as a preparation method and application of the conductive rubber material, and is applicable to the field of flexible sensors. The conductive rubber material is prepared from the following components in parts by weight: 100 parts of a rubber base body and 5 to 100 parts of conductive fillers, wherein the rubber base body is a rubber base body containing cis-1,4-isoprene structure; the conductive rubber material is prepared by dispersing the conductive fillers into a rubber material, radiating by electronic beams or gamma rays and crossly linking.

Description

technical field [0001] The invention belongs to the field of flexible sensors, and in particular relates to a conductive rubber material for flexible sensors and a preparation method and application thereof. Background technique [0002] A strain sensor is a device that can convert mechanical deformation information into electrical signal output such as resistance or capacitance. In 1885, the British physicist Kelvin discovered that when the metal undergoes mechanical deformation after being subjected to pressure (tension or torsion), the resistance value also undergoes a characteristic variation, which is called the strain-resistance effect. Inspired by this, people derive the characteristics and magnitude of the material's force from the change in resistance value, so as to manufacture so-called strain sensors, mainly including pressure strain sensors and tensile strain sensors. At present, metals, metal alloys and semiconductor materials with piezoresistive effect have b...
