1. A preparation method for water-loss-resistant ionic conductive gelatin hydrogel, wherein the preparation method comprising steps and conditions as follows:
Step 1: adding a predetermined amount of gelatin to deionized water, that is, soaking the gelatin in the deionized water so that the gelatin swells for a predetermined period of time, and causing the gelatin to swell and place the gelatin in a water bath and performing stirring with a magnetic force in the water bath at a predetermined temperature for a predetermined period of time to obtain a gelatin solution;
Step 2: obtaining a gelatin-sodium pyrrolidone carboxylate mixed solution in a process of adding sodium pyrrolidone carboxylate to the gelatin solution; and
Step 3: pouring the gelatin-sodium pyrrolidone carboxylate mixed solution into a mold to be cooled at a predetermined temperature for a predetermined period of time to obtain the water-loss-resistant ionic conductive gelatin hydrogel.
