Smart diaper moisture detection system described is a paper-based disposable moisture-activated RFID system that could be incorporated into the traditional cellulose-based diaper. The tag is semi-passive in the sense that it has no internal battery but incorporates a built-in energy conversion sensor (Action-Activated Tag). The tag with sensor unit is optimized for low-cost manufacturing, utilizes screen-printing with electrically conductive ink on paper-based substrates and inherits very low EM radiation. A discussion on the manufacturability and cost efficiency of the system is presented. A prototype system is shown and other possible application areas of the system are mentioned.
