Abstract
A three-dimensional fluidic assay device or sensor is described. The sensor has a porous substrate with a first face or plane defined along x-y coordinate axes, and a second face remote in a z-direction from the first face. The first face contains a sample deposition zone and the second face has at least one detection zone, such that when a fluid sample is deposited in the sample deposition zone, fluid is transported by means of capillary action along the z-direction to the detection zone and manifests a signal development. An absorbent article, such as a diaper or feminine hygiene product, having such a three-dimensional sensor integrated across the thickness of the absorbent article, from an inner layer to an outer layer, is also described.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
