  • Patent number: 8920731
    Abstract: A chemical gas sensor formed from a nonwoven material is described. The gas sensor includes a flexible, gas-permeable, nonwoven web-based material substrate having a matrix that is composed of a plurality of inert thermoplastic, pulp, cellulose or staple fibers as either a major or minor portion, with a plurality of gas-sensitive fibers formed from a polymer that can absorb volatile organic compounds (VOC), and a plurality of electrically conductive fibers. The gas-sensitive fibers are intermixed with and associated spatially among a network of adjacent electrically conductive fibers, such that a change in physical morphology of said gas-sensitive fibers as a result of interacting with volatile organic compounds, causes a change in dielectric properties that disrupts said network of adjacent electrically conductive fibers. The sensor can be configured as either a resistive or a capacitive chemisensor.

  • Patent number: 8866624
    Abstract: Signaling systems are disclosed that indicate a change in an absorbent article, such as the presence of a body fluid. The various different signaling systems disclosed do not include any conductive elements contained on the interior of the article as were required in the past. Instead, the changes are monitored from the outer cover of the article. In one aspect, for instance, a signaling device is provided for sensing and indicating the presence of a body exudate in an absorbent article, the device including a housing and a capacitive sensor disposed within the housing, the capacitive sensor adapted to sense a change in capacitance due to an insult to the absorbent article. The signaling device can include an attachment mechanism for removably attaching the housing to the absorbent article.

  • Patent number: 8866052
    Abstract: A heating article is provided including a heating element including a first layer of nonwoven fibers mixed with conductive fibers, wherein the layer is divided to include a conductive region and a nonconductive region, wherein the conductive region extends in a co-extensive and co-planar pattern in a majority of the layer, and wherein the conductive region has first and second ends, and a power source removably coupled to the first and second ends. The first layer can include nonwoven fibers mixed with non-metallic conductive fibers. The heating article can also include a second layer superposed with the first layer, wherein the second layer is substantially free of non-metallic conductive fibers.
