Patent ID: 7737322

Claim:
An absorbent article comprising: a chemiresistor disposed across a pair of spaced-apart electrodes, the chemiresistor comprising a plurality of electrically-conductive particles and a polymeric material; a microprocessor capable of detecting a change in an electrical property of the chemiresistor; and a means for signaling the presence of a change in the electrical property of the chemiresistor within the absorbent article; wherein the resistance of the chemiresistor is capable of changing when the chemiresistor is exposed to an analyte selected from the group consisting of water vapor, a volatile organic compound present in an insult, and combinations thereof, wherein the insult is selected from the group consisting of urine, menstrual fluid, feces, blood, and combinations thereof; and wherein the polymeric material is selected from the group consisting of polyepichlorohydrin, poly(N-vinyl pyrrolidone), polyisobutylene, poly(ethylene-vinyl acetate), ethyl cellulose, poly(diphenoxyphosphazine), and combinations thereof.
