ABSTRACT:
In general, the preferred form of the present invention comprises an electrical moisture sensing disposable baby diaper, having a moisture or liquid impervious outer sheet and a superimposed liquid permeable inner lining encapsulating a moisture absorbent wadding, and one single continuous electrically conductive material or two thin electrically conductive materials affixed flatly to one opposing surface between the outer sheet and the inner lining in an arrangement wherein a cavity comprising the feature of the touching of opposite inside surfaces is adjoined with one or more discrete securing means located within the central area respective the exterior margin of the absorbent wadding layer to provide a first and a second length of conduit of circuitry in said cavity respective the electrically conductive material, therefore to communicate with the inner lining and in the presence of moisture electrically short circuiting the electrically conductive materials, immediately signal the wet condition of the inner lining to an electrical alarm device appropriately connected to the electrically conductive materials. A second type of diaper of our invention includes an antenna of a separate electrically conductive material similarly affixed flatly to one surface of a conduit supporting sheet, to radiate to a distant wireless indicator the output of an electrical alarm device appropriately connected to the antenna and the electrically conductive materials. Physical separation of the electrically conductive materials, and the outer sheet to lining positioning arrangement within the diaper, is maintained by directly bonding together at one or more intervals, small portions of the various proximate and opposite surfaces of the outer sheet and the inner lining disposed central of the distance that one length of conductor is laterally removed from a similar length, or extending across, the individual electrically conductive materials, therefore to allow moisture or wetness to easily permeate around and between adjacent bonded portions of the inner lining, and across and throughout the absorbant material.
A third type of diaper of our invention includes an antenna of a separate electrically conductive material similarly affixed flatly to one of the surfaces of a conduit supporting sheet to radiate to a distant wireless indicator of an electrical alarm device appropriately connected to the antenna and the electrically conductive materials.
