Sensor products using conductive webs
First Claim
1. An absorbent article comprising:
- a chassis comprising an outer cover having an interior surface and an exterior surface and an absorbent structure positioned adjacent the interior surface of the outer cover, the chassis including a crotch region positioned in between a front region and a back region, the front region and the back region defining a waist region therebetween;
a current source configured to be releasably fastenable to the exterior surface; and
first and second conductive elements contained in the chassis and in electrical communication with the current source, the first and second conductive elements forming part of a circuit that is configured to conduct current from the current source in the presence of a substance that reduces the resistance between the first and second conductive elements, wherein the conductive elements include a conductive nonwoven web comprising conductive fibers.
