ABSTRACT:
A garment diaper detector for detecting wetness conditions in diapers or undergarments comprising a capacitive sensor located within a housing and affixed to the exterior surface of the garment being monitored. The sensor is comprised of two substantially solid, coplanar conductor plates affixed to a common substrate and has a very high dynamic range. The inside of the garment becomes wet, the capacitance between the spaced conductors rises above a predetermined value whereupon the detector provides an output to a transmitter or an alarm. When the garment is being changed, the detector is removed from the exterior surface of the garment for reuse on the next. In one embodiment of the invention, multiple, uniquely addressed wetness detectors are employed to monitor the wetness conditions in a plurality of garments, such as in a hospital or nursing home. When a garment becomes wet, that unique address is transmitted to a central monitoring station which dispatches a care giver to change the garment. Additionally, the central monitoring station may be equipped with a modem which communicates the address of wet garments to pagers worn by care givers.
