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 comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material. The wetness indicator is placed between the channel-forming areas or between at least one channel-forming area and at least one longitudinally extending side edge of the article, as seen for the exterior of the article.

A process for preventing multiplication of a bacteria, virus, or fungus, via: embedding Cu+ and Cu+++ ions into a material; contacting the bacteria, virus, or fungus with the material; and diffusing the Cu+ and Cu+++ ions into a cell and thereby reducing a biological energy-producing ability of the cell, via creating an inhibitory protein molecular structure degrading a membrane anatomy of the cell, thus suffocating the cell, thus protecting a skin from infection and preventing multiplication of the bacteria, virus, or fungus. Also described is a process for sensing: a load, a strain, or a liquid, on a fabric, that includes forming the fabric comprising a multi-walled nanomaterial tube copper bio-sensor via: spacing apart from one another, rows of multi-walled nanofibers, the rows of multi-wall nanofibers comprising copper; and spacing a continuous filament apart from and disposed substantially perpendicular to the rows of multi-walled nanofibers.

A method for manufacturing an absorption product includes a pre-processing step of decreasing a contact angle of a side of a first sheet, which has a plate shape and does not pass excretion, to a water by performing corona treatment on the first sheet, and a sensing pattern forming step of forming a sensing pattern that can transmit and receive a sensing signal indicating the excretion by printing or coating a conductive ink containing water on a side of the first sheet increased in hydrophilicity through the corona treatment.

Systems and methods for detecting a color of a color changing indicator in the presence of ambient light. A system includes a light source, a photodetector, and a processor. The processor obtains a first measurement of ambient light received from the photodetector while the light source is off. The processor causes the light source to transmit light. The processor obtains a second measurement from the photodetector during the transmission, the second measurement including the ambient light and the pulsed light reflected from an object. The processor determines a color of the color changing indicator by removing an ambient light signal from the second measurement based on the first measurement and therefrom determines a volume of bodily exudate present.

A nonwoven web for an absorbent article is provided. The absorbent article comprises the nonwoven web as a core wrap. A method for producing the absorbent article is also provided. The nonwoven web comprises a first nonwoven layer comprising filament fibers, a second nonwoven layer comprising filaments fibers, a third nonwoven layer comprising staple fibers disposed between the first and second nonwoven layers. A total basis weight of the first and second nonwoven layers is not less than about 10 gsm. The third nonwoven layer has a basis weight no greater than about 4 gsm. The nonwoven web comprises pores, wherein greater than about 80% of the pores have a pore size equal to or smaller than about 40 m, and wherein less than about 10% of the pores have a pore size equal to or greater than about 45 m.

An absorption product includes a sheet part having two or more patterns that are formed to be spaced apart from each other in an excretion area, which holds excretion of a user, and conduct electricity, and a terminal unit having three or more terminals physically being in contact with the patterns and being attached/detached to/from the sheet part, in which the terminals and the patterns may be formed such that at least one terminal physically comes in contact with each of the two or more patterns spaced apart from each other when the terminal unit is mounted on the sheet part, and a sensing module generating a sensing signal sensing the excretion and providing the sensing signal to the terminals being in contact with the patterns is provided in the terminal unit.

An absorbent article, such as a diaper or a training pant, having a wearer-facing side and a garment-facing side and a longitudinal axis. The absorbent article comprises a topsheet on the wearer-facing side, a backsheet on the garment-facing side, and an absorbent core between the topsheet and backsheet. The absorbent core comprises a generally longitudinally-extending channel. The absorbent article further comprises a wetness indicator at least partially superposed with the channel, as seen from the garment-facing side of the article.

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 electronic device having an indication member for determining liquid exposure in an electronic device is disclosed. The indication member may include ink and a layer covering the ink. The layer may include a liquid-permeable layer that allows liquid to pass through the layer and contact the ink. In this regard, at least some of the ink may rise through the layer and to a top surface of the indication member. Although the ink may be exposed at the top surface, in some cases, the ink is visible or detectable when exposed to light from an ultraviolet light source. Also, the top surface may include a pattern or other indicia that is also visible or detectable when exposed to the light source. When the indication member is exposed to liquid, the pattern may be altered or disturbed in a location corresponding to an exposed portion of the indication member.
