A diaper includes a diaper body and a wet diaper monitoring device, which includes a disposable pouch and a monitoring device. The monitoring device includes a monitoring casing, a first sensor electrode, a second sensor electrode, a sensing circuitry and an indicator. The first sensor electrode and the second sensor electrode are provided on an inner surface of and received in the monitoring casing, and form a single planar capacitor when the diaper body is dry. When the diaper body becomes wet, a capacitance between the first sensor electrode and the second sensor electrode increases substantially so as to transform the single planar capacitor of the first sensor electrode and the second sensor electrode into two much larger series connected capacitors.

Discloses herein are systems and methods for determining waste, such as urine or feces. Also disclosed herein are diapers incorporating a system as described herein for detecting waste, such as urine or feces, when worn by a subject.

A system includes a processor that executes computer executable components. The computer executable components include: a feedback component that receives sensory feedback data from a sensor device in association with wear, by a wearer, of an absorbent article to which the sensor device is attached; and a sizing component that determines whether a size of the absorbent article is appropriate for the wearer based on the sensory feedback data.

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 system includes a processor that executes computer executable components. The computer executable components include a battery monitoring component that monitors a power level of a power unit of a sensor device that removably attaches to an absorbent article configured to absorb and contain bodily exudates; and a notification component that generates a replacement notification based on a determination that the power level is below a threshold power level.

At least part of the conductor structures is in the base surface region. The first conductor structure and/or the electronic unit is joined with the first carrier layer region. The second conductor structure is joined with the second carrier layer region and coupleable electrically to the first conductor structure and/or the electronic unit by a layer stack surface region outside the electronic unit.

The present disclosure relates generally to a wearable device, and more specifically to a wearable device for detecting biological events, monitoring health condition of an individual, and for providing automatic alerts and analytics reporting. An exemplary wearable device for monitoring health condition of an individual comprises a puck component attachable to the individual's clothing, wherein the puck component comprises a circuit of a moisture sensor; a strip component configured to be placed within the individual's clothing, wherein a proximal end portion of the strip comprises a pair of conductive pads, and wherein the pair of conductive pads is configured to interface with the circuit of the moisture sensor while the proximal end portion of the strip is enclosed within the puck via a coupling mechanism.

The present invention discloses a method of manufacturing a diaper that has multiple moisture sensing elements on interior side of its bottom impermeable layer or on any surface of the top permeable layer. The moisture sending elements are made by spraying conductive ink on a moving sheet of either the bottom impermeable layer or the top permeable layer, before other layers of the diaper are attached. Spraying of conductive ink on the moving sheet causes parallel lines of conductive inks to be formed on the layer. The parallel lines of conductive ink run through the entire length of either of the layers and are designed to get connected with a detecting device. When a user urinates inside the diaper, the moisture causes a closed circuit between at least two of the parallel lines of conductive inks. These formations of closed circuits, between parallel lines of conductive inks, are detected by the detecting device. Also, with increasing volume of moisture, the resistance of the closed circuits also tends to decrease. This rate of decrease of resistance is also detected by the detecting device and is used to calculate a volume of moisture present in the diaper. The detecting device then generates a suitable alarm to give an idea about the saturation level of the diaper. The process of manufacturing sensing elements by spraying conductive inks on moving sheet of layer reduces the processing and modification overhead of specially designed conductive ink printers and also does not impact the manufacturing time of a diaper manufacturing assembly line.
