| 摘要 |
The article, especially as an absorbing napkin, includes inside at least a couple of electric leads (C1, C2) associated with at least a couple of external electric terminals which can be connected with electric means (SA, E, R, DS), suitable to: a) provide an electric potential difference between said leads during all the time in which the napkin remains dry, and besides b) causing a current passage between said leads and simultaneously the activation of an acoustic and/or luminous signaling device (DS) as soon as the napkin is impregnated with organic liquid, especially urines. |
