The invention provides a hydrogel driver with synergistic deformation and discoloration based on electric heating stimulation. The hydrogel driver at least comprises a composite structure of a flexible electric heating layer and fluorescent discoloration hydrogel, the flexible electric heating layer is a driving layer and has an electric heating conversion effect; the fluorescent color-changing hydrogel has a temperature response effect and is driven by the temperature of the flexible electric heating layer to synchronously deform and change color; during electrification, the flexible electric heating layer is heated to expand, the fluorescent color-changing hydrogel loses water after being heated, the volume of the fluorescent color-changing hydrogel shrinks, and the flexible electric heating layer is bent towards one side of the fluorescent color-changing hydrogel; meanwhile, the fluorescent color change hydrogel realizes the change of the fluorescent color. According to the technical scheme of the invention, the prepared electric measurement stimulation synergistic deformation color-changing polymer hydrogel driver realizes that the color changes while the fluorescent hydrogel driver drives, and overcomes the problem of non-synergistic deformation color change of the driver in the prior art.
