The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.
Claims20
A sensor system for detecting a property of or within an absorbent article, comprising:
- an absorbent article comprising a garment-facing layer and an absorbent assembly;
- a sensor;
- wherein the sensor is disposed in or on the absorbent article;
- wherein the sensor is separable from the absorbent article;
- wherein a portion of the sensor has a first width dimension and a second length dimension, wherein the first width dimension is at least 25.4 mm and the second length dimension is at least 50.8 mm;
- and
- wherein the sensor is an optical sensor;
- and wherein the absorbent article comprises a material placed against the garment-facing layer that reacts with urine or feces insult to change color which provides an optical indication for the optical sensor.
