Abstract

The application relates to devices (particularly diapers) for monitoring wetness of a subject. A pair of spaced electrodes (114) within an area subject to wetness couple non-conductively with a sensor (124) protected from wetness, and an alarm sounds in response to moisture decreasing the resistance between the electrodes (114). For example the electrodes (114) project into the absorbent material of a diaper and extend along the inside of the diaper sheath (110) opposite a pouch on the outside of the sheath (110). The pouch contains a sensor (124) capacitively coupled to the electrodes (114).
