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...
