Abstract
A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. 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;
- and
- wherein the sensor is an optical sensor;
- and wherein the absorbent article comprises a material that reacts with urine or feces insult to change color which provides an optical indication for the optical sensor, wherein the material that reacts with urine or feces insult becomes darker when liquid is introduced and becomes lighter as the liquid is absorbed by the absorbent assembly.
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 1.25 inches or the second length dimension is at least 2.25 inches;
- 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 change for the optical sensor to measure;
- and
- wherein the optical properties of the color-changing material exhibit a measurable degree between a first incontinent event and a subsequent incontinent event and the optical changes are reversible after each incontinent event.
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 1.25 inches or the second length dimension is at least 2.25 inches;
- 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;
- and
- wherein the optical sensor can provide information, based on the duration of the optical change, related to the amount of urine present in the absorbent article and/or the remaining absorbent core capacity of the absorbent article.
