Abstract
A diaper includes a diaper body and a wet diaper monitoring device, which includes a disposable pouch and a monitoring device. The monitoring device includes a monitoring casing, a first sensor electrode, a second sensor electrode, a sensing circuitry and an indicator. The first sensor electrode and the second sensor electrode are provided on an inner surface of and received in the monitoring casing, and form a single planar capacitor when the diaper body is dry. When the diaper body becomes wet, a capacitance between the first sensor electrode and the second sensor electrode increases substantially so as to transform the single planar capacitor of the first sensor electrode and the second sensor electrode into two much larger series connected capacitors.
