1. A system for monitoring an absorbent article designed to absorb and contain bodily exudates, the system comprising:
- an absorbent article comprising an optical property changing indicator adapted to change at least one optical property in response to the presence or absence of bodily exudates, wherein the absorbent article and the indicator form one integral unit; and
a detector device comprising a housing, a light source, a first optical sensor spaced from the light source, and a second optical sensor spaced from the light source and the first optical sensor,wherein the first optical sensor is positioned to detect the change of the optical property of the indicator at a first indicator location and corresponding absorbent article location, and the second optical sensor is positioned to detect the change of the optical property of the indicator at a second indicator location and corresponding absorbent article location that is different from the first indicator location and corresponding absorbent article location,wherein the absorbent article and the detector device is adapted to be associated together and disassociated from each other, wherein when the absorbent article and the detector device are associated together the detector device is adapted to detect the change of optical property of the indicator.

Abstract
The present disclosure provides an absorbent article for personal hygiene. More particularly, in one embodiment, the absorbent article absorbent article includes at least one property changing indicator. A detector device is also provided that includes at least one sensor. The sensor is adapted to detect the property change of the property change indicator in the absorbent article. In one particular embodiment, for example, the property changing indicator may include an optical property indicator such as a color change indicator and the sensor may include an optical sensor such as a color sensor.
