  • Disposable articles having a failure detection system
    Publication number: 20040064114
    Abstract: A system for detecting wetness in an absorbent article has an absorbent structure, at least one sensor in contact with the absorbent structure, a remote interrogating device, and a reporting element coupled to the interrogating device. The at least one sensor provides a variable electrical output dependent upon an amount of aqueous liquid associated with the absorbent structure. The remote interrogating unit is capable of detecting changes in the variable electrical output of the at least one sensor.
