Abstract
Water content sensing and informing system for a disposable diaper consisting of water permeable inner sheet, water absorber, and water impermeable outer sheet, comprises at least one pair of metal layers, one surface of one layer being covered with an electric insulating layer, formed between the water impermeable outer sheet and the water absorber, a detector for detecting water content absorbed in the diaper, and an informing mechanism for informing the detected result. The pair of metal layers is isolated with constant distance to each other and extended in the longitudinal direction of the diaper. The pair of metal layers is formed in a thin layer by a lamination or vacuum evaporation of a metal leaf. The informing mechanism is selected from a visual, auditory, remote informing device using an oscillator and receiver, or combination of these.
