Abstract: An insert for sensing a bodily fluid or condition and for use in conjunction with an undergarment or a disposable absorbent article is provided, the insert including a first substrate having a first substrate article-facing surface and a first substrate body-facing surface, a second substrate having a second substrate body-facing surface, and an absorbent element disposed between the first and second substrates. The insert also includes two conductive elements disposed between the second substrate body-facing surface and the first substrate article-facing surface, wherein the conductive elements are adapted to be removably connectable to a signaling device. Also provided is an insert including a first substrate having a first substrate article-facing surface; and two conductive elements disposed on the first substrate, wherein each conductive element comprises conductive paper or tissue, and wherein the conductive elements are adapted to be removably connectable to a signaling device.
