The present invention relates to disposable absorbent articles. The disposable absorbent articles include: (a) a body contacting surface; (b) a garment contacting surface opposite the body contacting surface; and (c) an inkjet printed wetness indicator which is seen through either the body contacting surface or the garment contacting surface. The wetness indicator includes a central graphic and a background graphic, the central graphic having at least one permanent ink composition and the background graphic having at least one water soluble ink composition.

A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.

An absorbent article includes a liquid permeable, apertured topsheet, a liquid impermeable backsheet, an absorbent core disposed at least partially intermediate the topsheet and the backsheet, and an acquisition material disposed at least partially intermediate the topsheet and the absorbent core. The acquisition material has a caliper in the range of about 2.5 mm to about 10 mm, according to the Caliper Test, and an Air Permeability in the range of about 5,000 l/m.sup.2/s to about 11,000 l/m.sup.2/s, according to the Air Permeability Test. The acquisition material has a first surface, a second surface, and a plurality of three-dimensional features extending outwardly from the first surface or the second surface.

The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

The invention provides an absorbent article comprising an indication means for indicating the presence of bodily exudates, the indication means comprising a color-changing indication means, wherein the absorbent article and the indication means form one integral unit, the article further comprising a indication device, which comprises a housing and a connection means, such that the indication device can be attached to the absorbent article and be detached from the absorbent article, wherein the indication device comprises a color sensor.

A disposable diaper product useful for collecting a urine sample from an infant is disclosed. In one example the product may have a liquid control structure overlying a liquid impermeable backsheet, with a plan surface area defining a volume coextensive therewith, wherein a portion of the volume defined by at least 50 percent of the plan surface area contains no more than 50 percent by weight absorbent material. In another example the product may have a liquid control structure overlying a liquid impermeable backsheet, and have an average Liquid Release Ratio of at least 3 percent. A method for collecting a urine sample from an infant is also disclosed, in which a diaper is used for collection.

An absorbent article comprising a topsheet, a backsheet, and a layer of absorbent material interposed between the topsheet and the backsheet is provided. The layer of absorbent material comprises superabsorbent polymer. The absorbent article comprises a lower acquisition and distribution system with at least one nonwoven or woven layer. The lower acquisition and distribution system is interposed between the layer of absorbent material and the backsheet. The absorbent article comprises a wetness indicator composition.

The present disclosure is directed to techniques for coupling activation of sensor devices with use of authorized products. A system includes a sensor device. The sensor device includes a housing that attaches to an absorbent article configured to absorb and contain bodily exudates. The sensor device further includes at least one sensor formed on or within the housing configured to capture sensor data in association with wear of the absorbent article. The system also includes a processor that executes computer executable components. The computer executable components include a communication component that receives an activation code and an activation component that activates a functionality based on the receipt of the activation code.

A system includes an absorbent article that absorbs and contains bodily exudates and comprises an indication unit that generates an optical signal indicative of presence of the bodily exudates within the absorbent article. The indication unit comprises an optical property changing element that changes from having a first optical property to having a second optical property in response to exposure to the bodily exudates. The indication unit further comprises a visual modifying element proximate that provides a visual modification to the second optical property, resulting in the optical signal comprising a third optical property, wherein a sensor device that attaches to the absorbent article detects the presence of the bodily exudates based on recognition of the optical signal comprising the third optical property.
