Abstract

A compact self-contained bedwetting alarm uses intermittent vibration to awaken the user. Sensors on the surface of the alarm enclosure sense the presence of urine and activate a low frequency vibration. The vibration is turned on and off by a timer so that the user is not lulled to sleep by the vibration. The alarm may be worn in close proximity to the source of urine. There are no external wires to entangle, and the position of the alarm close to the source of urine reminds the user to control the emission of urine when the alarm is on.
