▎ 摘　　要

NOVELTY - A capacitive electrocardiogram signal collecting composite film comprises a flexible insulating substrate, electrodes provided on the flexible insulating substrate, a semiconductor two-dimensional material arranged on the electrode, and an electrolyte polymer layer provided on the semiconductor two-dimensional material. USE - Composite film is used for capacitive electrocardiogram signal collecting device (claimed). ADVANTAGE - The electrodes in the capacitive electrocardiogram signal collecting composite film are modified by semiconductor two-dimensional materials, and flexible metal electrode/semiconductor two-dimensional material is formed to increase area of electric double layer on contact surface of flexible electrolyte polymer layer, such that capacitance value of the composite film, and collecting quality of the signal are improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite film.
