Abstract
Absorbent articles incorporating a wetness sensor for indicating the presence of a body fluid are disclosed. The wetness sensor includes an olfactory signaling device that produces a scent or odor when a body fluid is detected. For instance, in one embodiment, an odorous composition can be contained in a water degradable pouch that releases the odorous composition when contacted with moisture. Once released, the odorous composition can produce a desired scent. In other embodiments, the odorous composition can be encapsulated within a water degradable material or can be coated on a substrate. The scent or odor that is released by the odorous composition can vary depending upon the particular application. The scent, for instance, may be pleasant or unpleasant. In one embodiment, the olfactory signaling device may be used to assist in toilet training a child.
