    Patent number: 8962909
    Abstract: The invention relates to a moisture detecting module for monitoring a moisture state of a napkin. The module comprises a moisture sensitive sensor and a moisture non-permeable layer covering the sensor. The moisture non-permeable layer is arranged for attachment to a napkin surface that, during use of the napkin by a person, is facing towards the person's skin such that the moisture sensitive sensor contacts the napkin surface. The moisture detection module is a RLC circuit that acts as a RF-tag thereby transmitting moisture information to a remote reading device.
