▎ 摘  要

NOVELTY - Sensing storage integrated bionic tactile fiber comprises a conductive fiber base layer (1), base modified layer (2) covered on the conductive fiber base layer periphery, storage function layer (3) coated on the periphery of the substrate modification layer and sensing function layer (4) covered on the periphery of the storage function layer, where the one end of the outer surface of the sensing function layer is provided with conductive fiber upper electrode (5). The material of the storage function layer is memristor function material and the sensing function layer is made of the material of pressure sensitive material. USE - Sensing storage integrated bionic tactile fiber used for tactile sensing system. ADVANTAGE - The fiber integrates a tactile sensor and a memristor two-type function separating device to realize sensing and storing function of haptic information, thus improving speed and efficiency of information processing in a haptic sensing system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a sensory storage integrated bionic tactile fiber, which involves: (A) dissolving the conductive material in naphtha, ultrasonically treating for 1-3 hours and then stirring for 0.5-2 hours to obtain a conductive material solution with a conductive material concentration of 0.1-5 wt.%, placing the flexible fiber substrate on it, immersing and stirring in the above conductive material solution for 5-60 minutes, and drying at room temperature to prepare a conductive fiber base layer; (B) adding the base modified layer material to deionized water, fully stirring and dissolving at room temperature to prepare a base modified layer solution with a concentration of 0.05-5 wt.% base modified layer material, placing fibrous base layer in the above-mentioned base modified layer solution for 5-10 minutes, and drying at room temperature to prepare conductive fiber base layer wrapped by the base modified layer; (C) adding the memristive material into deionized water, ultrasonically treating the material until the material is dispersed to obtain an aqueous solution of the memristive material with a concentration of 0.1-5 wt.%, immersing the conductive fiber substrate wrapped by the substrate modified layer in the memory after 5-30 minutes in the barrier material aqueous solution and drying at room temperature, repeating the above dipping operation multiple times to prepare the storage functional layer; (D) taking single-phase sensitive material or take two-phase sensitive material according to the ratio of 1:0.3-4, dissolving the taken sensitive material in 10mL naphtha, ultrasonically dispersing for 1-3 hours, magnetically stirring for 0.5-2 hours, then adding to the matrix, subjecting material to magnetic stirring treatment for 0.5-2 hours to obtain a sensitive material solution with a concentration of 5-50 wt.% sensitive material, immersing conductive fiber base layer covering the storage function layer in the above-mentioned sensitive material solution, treating for 5-10 minutes, vacuum drying to prepare sensing function layer; and (E) wrapping the conductive fiber base layer or gold wire or silver wire prepared on the conductive fiber base layer wrapped with the sensing function layer to obtain product.
