Description

technical field [0001] The invention belongs to the field of flexible sensors, and in particular relates to a conductive rubber material used for flexible sensors, a preparation method and application thereof. Background technique [0002] A strain sensor is a device that can convert mechanical deformation information into an electrical signal output such as resistance or capacitance. In 1885, the British physicist Kelvin discovered that when a 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 obtain the characteristics and magnitude of the material's force from the change in resistance value, thereby manufacturing so-called strain sensors, mainly including pressure strain sensors and tension strain sensors. At present, metals, metal alloys, and semiconductor materials with piezoresistive effects ...
