摘要： The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.
