NOVELTY - Preparing bipolar electrochemical light emitting sensor, involves (a) fully mixing ferric chloride, conductive material and acrylic acid to get a mixed solution 1, which is fully mixed with gelatin at 45-55℃ to get the mixed solution 2, (b) thoroughly mixing silver nitrate and mixed solution 2 to obtain mixed solution 3, passing nitrogen to remove the dissolved oxygen contained in the mixed solution 3 to obtain a mixed solution 3 deoxygenated, polymerizing with a mixture of ammonium persulfate and deoxygenation 3 to obtain a conductive hydrogel, (c) modifying hydrogel with luminescent agent by replacing the conductive material with a luminescent agent to prepare a hydrogel with a luminescent function, (d) wrapping the conductive hydrogel on one end of luminescent hydrogel and self-healing to form a self-healing hydrogel based on c-BPE, where one end of the hydrogel wrapped with a conductive function is used as the cathode, and the other end is used as the anode. USE - Method for preparing bipolar electrochemical light emitting sensor used in the preparation and analysis of motion behavior, voice recognition and/or detection of liquid components, where motion behavior is the motion amplitude and/or motion time (claimed). ADVANTAGE - The method provides excellent stretchability, adhesion, and strain sensing properties of hydrogels, and the high sensitivity, stability, and accuracy of bipolar electrochemiluminescent sensing platforms.
