The invention discloses a stretchable adhesive conductive structure color hydrogel film and a preparation method thereof, the method is based on a photonic crystal positive structure template, an inverse opal structure hydrogel film is prepared by a template sacrificial method, a precursor solution of the adhesive conductive hydrogel is filled in the gap of the inverse opal hydrogel film, and the adhesive conductive structure color hydrogel film is obtained after curing, so that the operation is simple, the cost is low, the reuse is realized, and the convenience and the reliability are realized; the conductive structure color hydrogel film prepared by the method has good conductivity, firm adhesion and affinity to skin, has the characteristic of double-signal response to mechanical movement, can be used as a double-signal sensor for human body movement, and feeds back structural color sensing and electric signal sensing in real time according to the change of the human body movement. |
