  • Faecal detection sensor
    Patent number: 11280757
    Abstract: The invention provides the present invention provides a faecal detection sensor for an absorbent article. The sensor includes a faeces-sensitive material that reacts to the presence of a constituent of faecal matter, wherein the sensor exhibits an electrical property that changes following the reaction of the faeces-sensitive material. In embodiments of the invention the faeces sensitive material is a material that reacts due to the presence of a sulfur-containing compound in faecal matter, such as metallic faeces-sensitive materials, or is a material that reacts with a faecal enzyme and/or other constituents of faecal matter, such as organic faeces-sensitive materials.
    Type: Grant
