The invention provides a preparation method of high-toughness, high-sensitivity and self-adhesion conductive hydrogel. The preparation method comprises the following steps: S1) mixing a macromolecular micelle cross-linking agent Brij-100A with monomer acrylic acid, and carrying out ultrasonic treatment; s2) adding a certain amount of thermal initiator ammonium persulfate and deionized water into the solution obtained in the step S1), and then performing ultrasonic treatment to the mixed solution; s3) adding a certain amount of conductive substance and mixing with the MXene aqueous solution; and S4) injecting into a glass mold, and heating at 50 DEG C for 10 hours to obtain the conductive hydrogel material. The material prepared by the invention has excellent mechanical properties, and can well meet the requirements of wearable sensors; the sensor has high sensitivity, can accurately detect human motion, has self-adhesion performance, and can be well attached to a human body; a strong micelle cross-linked hydr
