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.

A personal hygiene product with a digital element is described. In one embodiment, a conductive sensor assembly is disposed within the personal hygiene product that includes one or more moisture sensors that generate a resistive and/or capacitive signal indicative of saturation of the personal hygiene product when in wetting contact with menstrual fluid.

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.

Disclosed herein are devices, wound dressings and methods for determining the pH of fluid or a wound exudate at a wound. Example devices include a device comprising a surface configured to contact the fluid or wound and a pH indicator covalently bound thereto or applied to the surface, wherein the pH indicator has a first colour prior to contact with the fluid or the wound exudate and changes colour as a function of the pH of the fluid or wound exudate. Example devices include a device which indicates wound exudate loading within a wound dressing and wound dressing comprising an absorbent layer and a moisture indicator which indicates would exudate loading within the dressing, wherein the visibility of the moisture indictor changes as a result of a physical transformation of a first material within the dressing. Systems, devices, and methods are provided for monitoring wound status and progression by measuring pH levels indicated by pH-sensitive wound dressings. In some implementations, a wound is monitored by capturing an image of the pH-sensitive wound dressing and processing the captured image to determine the color of a pH indicator included on the wound dressing. The color of the indicator is determined in terms of RGB values from the image, and a pH value for the wound dressing is calculated from the dressing RGB values. The calculated pH value is then relayed to a user to be used as an indicator of wound status or health.

Absorbent articles with biodegradable and/or biocompostable elements are disclosed, wherein the absorbent articles include sensors. The sensors detect and determine variables associated with collected fluids, solids, and gases, including a presence of fluids, solids, and gases, a volume of fluids, solids, and gases, and/or a distribution of fluids, solids, and gases. In one embodiment, the sensors and/or connected computing systems are calibrated to capacities and other properties of elements within the articles, including superabsorbent polymers, and are operable to trigger an alert based on detected or determined conditions.

An ultra-high frequency (UHF) wireless sensor includes an agent activated non-metal antenna formed of a conductive stimuli-responsive hydrogel material. A radio frequency identification (RFID) tag in electronic communication with the non-metal antenna includes a wireless data communication integrated circuit (IC). The non-metal antenna is configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent.

Sensor devices and systems for monitoring the basic needs of an infant comprising feeding, sleeping, and/or voiding (urinating and/or defecating) are described herein.

A personal hygiene device may have a main body with an absorbent material configured to absorb a fluid, a sensor disposed within the main body, and a controller configured to communicate with the sensor. The sensor has a conductor and an insulator containing at least a portion of the conductor, and the sensor is configured to detect a first electrical value and a second electrical value that is different from the first electrical value. The sensor is also configured to transmit a signal to the controller upon detection of the second electrical value.
