摘要：
The present invention relates to a system suitable for monitoring multiple leakage events such as wetting of a diaper or alike sanitary product. The system includes two or more than two electrodes that are supported in a spaced apart relationship and a liquid permeable substrate between the electrodes that lacks or has a low capacity for holding or storing liquid. In the event of liquid leakage, an electrical bridge connecting the electrodes can be formed by the liquid, and before the product becomes saturated liquid can freely drain from the permeable substrate and disconnect the electrodes. Upon further liquid leakage, electrical connection between the electrodes can be reformed indicating multiple liquid leakage events. In the situation where the sanitary product becomes saturated and liquid is prevented from draining from the permeable substrate, the electrical connection will continue, indicating that the sanitary product requires changing.
