Abstract: An absorbent structure, including a sensor system, can sense and measure the level of wetness contained within the absorbent structure as well as sense and measure environmental conditions. The sensor system may include passive RFID sensors or tags, RFID readers, antenna, a tuning module, a processing module, a memory module and a wireless communication module. The absorbent structure may further include two or more sensors, with a first sensor placed in a first area most likely to first be exposed to liquid and a second sensor spaced apart from the first sensor in an area likely to be exposed to liquid only after the absorbent structure has become more saturated.

Abstract: A mattress (100) includes one or more layers (101,102,103) of material, and one or more pressure sensors (104,105,106). A control circuit (203), operable with the pressure sensors, is operable with a user interface (115). The control circuit presents on the user interface one of three color-coded indications. When a sensed pressure detected by the pressure sensors is below a first threshold (603), the control circuit presents a first color-coded indication on the user interface. When the sensed pressure (605) is between the first predefined sensor threshold and a second predefined sensor threshold (604), the control circuit presents a second color-coded indication on the user interface. When the sensed pressure is above the second predefined pressure threshold, the control circuit presents a third color-coded indication on the user interface.
