Abstract: A capacitive sensing film, a smart diaper and a wetness detection system device including the capacitive sensing film. The capacitive sensing film includes a metal film electrode, a flexible substrate, and a waterproof protective layer; the metal film electrode is deposited on the flexible substrate, and the waterproof protective layer covers the metal film electrode and forms an interlayer, adapted to protect the metal film electrode; the metal film electrode has a smooth surface and a nanoscale thickness, adapted to reduce the surface area in contact with a liquid through the gap of the interlayer; when the capacitive sensing film is wetted by the liquid containing electrolyte, the electric double layer capacitance generated between the metal film electrode and the liquid is smaller than the electrolytic capacitance generated between the metal film electrode and the liquid, thus a wetness detection function based on electrolytic capacitance is realized.
