An absorbent article includes: a liquid-absorbent body; a liquid-permeable sheet disposed on a skin side in a thickness direction of the absorbent article with respect to the liquid-absorbent body; a liquid-impermeable sheet disposed on a non-skin side in the thickness direction with respect to the liquid-absorbent body; one or more skin-side electrodes between the liquid-permeable sheet and the liquid-absorbent body; and one or more non-skin-side electrodes between the liquid-impermeable sheet and the liquid-absorbent body.

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.

A diaper with urine detection functionalities is provided. The diaper includes a urine isolation layer, an absorbent core layer, and an outer layer. A urine detection device is disposed between the urine isolation layer and the absorbent core layer. The isolation layer has an open end that is embedded in a sleeve of the absorbent core layer. The urine detection device comprises a detection circuit and a test paper composite. The test paper composite includes: a trace element test paper, an antibiotic test paper, and a urine routine test paper. Each test paper is made up of a plurality of test strips for detecting different elements. Each test strip produces results according to a different color indicator scheme.

An incontinence detection pad has an RFID tag in which an authentication code, such as an electronic product code (EPC), is stored. A reader in wireless communication with the RFID tag of the incontinence detection pad verifies that the incontinence detection pad is an authorized detection pad. Thus, unauthorized incontinence detection pads that do not have the proper authentication code are not able to be used in an incontinence detection system.

An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay. After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.

The present invention relates to a sanitary diaper or undergarment having a body shield that may be made of a plurality of materials and may be infused with a plurality of substances that have anti-fungal, anti-bacterial and moisturizing properties. The body shield may be hypoallergenic, scented or non-scented. The interior of the body shield has an adhesive flap that can be applied to the genital area or hip area of the wearer, in order to seal the genital area or hip areas of the wearer from any human waste that accumulates within the diaper. As a result, the device greatly reduces and prevents the occurrence of diaper rash and other skin irritations that can occur from wearing a diaper for prolonged periods of time.

An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.

A package comprising a plurality of disposable absorbent articles contained in an outer wrap is disclosed. The outer wrap is formed of a film having a thickness and has a path of scoring that partially but not completely penetrates the thickness, and defines a path of weakness in the film along which tear propagation is facilitated.

The current invention concerns to an absorbent article (100) comprising a first part being a disposable part (10), and a second part being a re-usable part (20) wherein the re-usable part (20) is configured to removably hold the disposable part (10), and wherein the absorbent article (100) comprises an electronic system (22) configured to measure data related to a wearer of the absorbent article, and/or to the absorbent article and/or to ambient conditions in close proximity to the wearer of the absorbent article.
