The invention belongs to the technical field of hydrogel, and discloses transparent conductive hydrogel with single-sided self-adhesion as well as a preparation method and application thereof. The method comprises the following steps: adding an anionic surfactant into deionized water, conducting stirring at 30-80 DEG C, then adding methacrylic acid long-chain alkyl ester, conducting stirring at 10-40 DEG C, then adding acrylic acid, conducting magnetic stirring until the acrylic acid is completely dissolved, adding an initiator and acrylic acid short-chain alkyl ester, continuing stirring to realize uniform mixing, carrying out ultrasonic defoaming on an obtained solution, pouring the solution into a glass mold, carrying out reacting at a temperature of 50 to 70 DEG C to obtain the transparent hydrogel with single-sided self-adhesion, completely soaking the hydrogel in a mixed solution of ferric chloride and citric acid, taking out the hydrogel and washing the hydrogel. The hydrogel has unique single-sided self-adhesion, high strength, large deformability and good conductivity and transparency, can be used as a strain sensor, and has wide application prospects in the fields of electronic skin, intelligent wearable equipment and the like.
