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