An absorbent core comprising a front portion; a back portion; a middle portion positioned between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core being a multi-layer core comprising at least two distinct core layers, wherein a first core layer comprises a first concentration of super absorbent polymer therein and a second core layer comprises a second concentration of super absorbent polymer therein said first and second concentrations being different, wherein at least said first core layer comprises one or more channels, said channel(s) being continuous and interconnected at least along the length and the width of said core such that at least two channel portions extending along said length are in fluid communication via a connecting channel portion positioned proximal to said back portion.

An absorbent core comprising: a front portion; a back portion; a middle portion position between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core comprising an absorbent material sandwiched between upper and lower layers of said core wherein the absorbent core comprises at least one interconnected channel substantially free of absorbent material and with at least portions thereof extending along both the length and the width of said core arranged to form an open end proximal to the front portion and a closed end proximal to the back portion and wherein said channel is formed by mechanically bonding said upper layer directly to said lower layer at a plurality of distinct bonding sites, wherein each channel portion comprises no more than two consecutive bonding sites taken along a channel width axis.

Remotely detecting the presence of urine or feces in a diaper of an infant or adult using a disposable sensor placed inside the diaper, in conjunction with a permanent device that is capable of wirelessly transmitting data to a mobile device or base station is disclosed. The permanent device can also be capable of measuring temperature and body movements. This additional information can be used in conjunction with the detection of urine or feces to identify patterns.

The invention provides an absorbent article comprising an indication means for indicating the presence of bodily exudates, the indication means comprising a color-changing indication means, wherein the absorbent article and the indication means form one integral unit, the article further comprising a indication device, which comprises a housing and a connection means, such that the indication device can be attached to the absorbent article and be detached from the absorbent article, wherein the indication device comprises a color sensor.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

A diaper sensor for detecting and differentiating feces and urine in a diaper is described. The diaper sensor may include at least one pair of conductive elements positioned within an absorbent region of the diaper. The diaper sensor may also include a transmitter and a control circuit operatively connected to the at least one pair of conductive elements and the transmitter. The diaper sensor may further include a power source operatively connected to the control circuit. The control circuit may measure the conductivity between the at least one pair of conductive elements. The control circuit may also determine whether there is poop or pee present in the diaper using the conductivity. The control circuit may also transmit via the transmitter a signal indicative of whether there is excrement or pee present in the diaper.
