A wound dressing includes at least one sensor generating a sensor signal. The wound dressing also includes a display configured to receive the sensor signal from the at least one sensor and present data corresponding to the sensor signal.

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.

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.

Incontinence management systems, methods, and sensors are provided that alert the caregiver when a patient's brief has been soiled. A resonant circuit includes a polyaniline/carbon black (PANI/CB) composite chemiresistor which undergoes a large impedance change upon exposure to the vapor or smell of urine or feces. Due to the impedance change of the PANI/CB resistor, characteristics of the resonant circuit change when the sensor is exposed to urine or feces vapor. The sensor responds to an interrogating signal with a signal based least in part on the sensor's impedance and indicates the condition of the brief as soiled or clean.

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.

A liquid indicating article is disclosed. It can have a single layer, but generally will have at least two layers bonded together, wherein a visible layer masks a second colored layer wherein the visible layer is a wicking material that becomes semitransparent when wet, wherein the colored layer is a permeable adhesive that bonds to the mask layer.

An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the article further comprises at least two volume indicators, and wherein at least one volume indicator comprises a masking layer comprising a water-soluble colorant and a stationary color layer comprising a permanent colorant.

This replacement necessity assessment apparatus for an absorbent member includes: a power generator which is configured to generate power as a result of contact with liquid absorbed in the absorbent member, and of which power generation amount changes in accordance with an amount of the liquid; a signal output unit configured to output a detection signal according to the power generation amount; and a processing unit configured to acquire a parameter regarding the amount of the liquid based on the detection signal, the processing unit configured to determine, based on the parameter, whether or not replacement of the absorbent member is necessary.

A liquid indicating article is disclosed.

A hot melt wetness indicator composition that includes a water insoluble thermoplastic polymer, an anionic surfactant, a leuco dye, and a component selected from the group consisting of acid, rosin-based tackifying agent, plasticizer and combinations thereof, and is homogeneous is disclosed. The hot melt wetness indicator composition exhibits a color change after contact with water.
