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 absorbent article is worn to receive discharged urine of the wearer. The article includes a liquid-permeable top sheet, an intermediate liquid-absorbent layer, a bottom sheet including at least one indicator and a liquid-impermeable backing layer. Each of the at least one externally visible indicator is coated or impregnated with at least one chemical reagent facing the liquid-absorbent layer. Each of the at least one chemical reagent is configured to undergo a change in color or shade from a plurality of different possible color or shade changes of the reagent upon contact with the discharged urine. Each color or shade is associated with a corresponding level of an analyzed component or with the presence or absence of the analyzed component and the change in color or shade of the at least one chemical reagent is externally visible on the indicator through the bottom sheet and the backing layer.

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.

Various examples are described for detecting heart rate and respiratory rate by using measurements of light applied to skin through an article. For example, a sensor application obtains a set of measurements of light. The application compensates for a contribution of the article based on one or more known optical properties of the article. The sensor application further determines, from the set of measurements of light, a periodic change in amplitude. The sensor application identifies the periodic change in amplitude as a heart rate having an identical periodicity. The sensor application identifies a respiratory rate as equal to the rate of change of the heart rate.

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.

A disposable diaper having a first sheet of viscose fiber material disposed against a child's skin, an acquisition and diffusion layer (ADL) interposed over top of the first sheet of viscose fiber, a coating layer of tissue fiber interposed over top of the ADL layer, an absorbency core layer interposed over top of the coating layer, a permeable layer of polymer film interposed over top of the absorbency core layer, and a second sheet of viscose fiber material overlaid over top of the permeable polymer film layer, the second sheet functioning as the exterior sheet of the disposable diaper.
