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.
