NOVELTY - Preparing high-elasticity hydrogel sensor involves adding first monomer into water, and uniformly stirring at 45-55degrees Celsius to obtain solution A. The conductive filler is added into solution A, and uniformly mixed at normal temperature to obtain solution B. The second monomer is added into solution B, and uniformly mixed at normal temperature to obtain solution C. The initiator, cross-linking agent and catalyst are added into solution C, and uniformly mixed at normal temperature to obtain solution D. The solution D is poured into sealed mold, and placed sealed mold into drying oven with temperature of 35-65degrees Celsius for heat preservation and solidification for 3-6 hours to obtain high-elasticity hydrogel sensor. USE - Method for preparing high-elasticity hydrogel sensor. ADVANTAGE - The method enables to have interpenetrating structure, high elasticity, and accurately and effectively sense the size, shape and position of force.
