A wet diaper detector comprises an elongated strip of material sized to be positioned in a diaper with a portion of the strip residing in a region of the diaper subject to wetness and an end of the strip protruding from the diaper at the upper rear or front portion thereof. The strip carries a pair of spaced conductors that extend along the length of the strip and terminate at the protruding end thereof. A detector and alarm assembly is adapted to be releasably coupled to the protruding end of the elongated strip and is configured to monitor the electrical resistance between the spaced conductors of the strip. When the diaper is wet by its wearer, the resistance between the spaced conductors of the strips falls below a pre-established value whereupon the detector activates the alarm to alert an attendant to change the diaper. In one embodiment, wetness is detected capacitively. When the diaper is changed, the detector and alarm assembly is decoupled from the strip for reuse and the strip is discarded along with the soiled diaper.

[ I claim:] [1.] A wet diaper detector comprising a diaper having a liquid impermeable exterior surface, a housing for containing operative components of said detector with said housing having a surface configured to be positioned against the impermeable exterior surface of the diaper, an adhesive patch for removably mounting said housing to said exterior surface of said diaper with said surface of said housing held against said diaper impermeable exterior surface, sensor means located on said surface of said housing for sensing a wet condition on the inside of said diaper while being located outside the diaper where said sensor means does not contact wetness within the diaper, and electronic means in said housing operatively coupled to said sensor means for producing an alarm upon the sensing of a wet condition inside the diaper.
