ABSTRACT:
An apparatus which is worn to condition the wearer against bed wetting is disclosed. The apparatus includes a wetness sensor that has a circuit pattern in which a multiplicity of interleaved, spaced apart conductive fingers reside on a non-conductive substrate. The circuit pattern is optimized to quickly and reliably detect small quantities of urine. The substrate is curved into a three dimensional, cup-like shape which has an edge that conforms to the urogenital area of the wearer. A foam pad is positioned at this edge to help seal the wetness sensor against the wearer and to make the wetness sensor comfortable to wear. Electrical components couple to the wetness sensor and drive a speaker. The electrical components include a battery and a relay. The realy is configured to oscillate when the wetness sensor detects urine, and the oscillating relay causes the speaker to broadcast an alarm signal.
