An apparatus and a system for a smart diaper are described. These smart diapers include a disposable detection component and a reusable component including various processing circuitries. The disposable component can include a paper printed sensor pad. Paper printed sensor pads can provide for a wide detection area, and accurate determination of whether human waste is present in the diaper. Additionally, the sensor pad can determine the amount of waste exposed to the sensor pad. In certain embodiments, the sensor can also detect a temperature within the diaper. In some embodiments, the smart diapers can provide for location tracking of the wearer of the diaper, and provide notifications to the caretaker based on the location of the wearer. In some embodiments, the reusable component can be a small circular component which is mounted on the outside of the smart diapers.

A soiled diaper detection system having a soiled diaper detection device, one or more computer devices in communication with the diaper detection device configured to generate and process requests to the diaper detection device, and store data received from the soiled diaper detection device.

An absorbent article having an outer cover with an interior surface and an opposite exterior surface, an absorbent core positioned adjacent the interior surface of the outer cover, and a wetness indicator graphic located on the outer cover. The wetness indicator graphic has a permanent graphic defining at least one non-printed area and a changing graphic located within the at least one non-printed area of the permanent graphic such that the permanent graphic and the changing graphic together give the appearance of a uniform graphic.

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.

A combined apparatus for indicating the elevated temperature of an infant and for sensing moisture in a diaper. The combined apparatus includes an elongated sensing strip made of highly efficient liquid absorption and transfer capillary wick material having a first end disposed in engagement with the diaper. The elongated sensing strip has a first side having a pair of screen-printed, spaced apart conductive ink bands which couple electrically at one end with a portable alarm unit and a second side having an elongated band of thermochromic ink printed thereon a segment of which is visible proximate the second end of the elongated sensing strip.

An absorbent article having an outer cover with an interior surface and an opposite exterior surface, an absorbent core positioned adjacent the interior surface of the outer cover, and a wetness indicator graphic located on the outer cover. The wetness indicator graphic has a permanent graphic defining at least one non-printed area and a changing graphic located within the at least one non-printed area of the permanent graphic such that the permanent graphic and the changing graphic together give the appearance of a uniform graphic.

The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

There is provided an auto detection system including a thermal detection device and a host. The host controls an indication device to indicate a prompt message or detection results according to a slope variation of voltage values or 2D distribution of temperature values detected by the thermal detection device, wherein the voltage values include the detected voltage of a single pixel or the sum of detected voltages of multiple pixels of a thermal sensor.

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.

A system for monitoring one or more patients has: i) a number of temperature sensors for attachment to the outer surface of an absorbent article at spaced locations for generating a number of signals indicative of the temperature measurements at such locations; ii) a transmitter for communicating the signals to a processor; iii) wherein the processor is provided with computer code which, when executed, determines whether a urination or defecation event has occurred in the absorbent article based on the temperature measurements; and iv) a display for displaying the urination or defecation event to a care-giver. An accelerometer can also be used to provide additional information of use to the caregiver in combination with incontinence information.
