Abstract
An apparatus which detects urination by a user includes a urine sensing pad for placement over the pubic and/or perianal areas of a user. The sensing pad includes a pair of electrodes on a backing sheet, and an absorbent cover sheet which is glued or heat sealed to the backing sheet. An indicator box is carried by the user and coupled to the sensing pad for generating a digitally encoded signal when urine moistens the pad and completes a circuit which includes the electrodes. Either a local alarm or remote signal is triggered by the indicator.
