Abstract

An incontinence detection device comprising a pad with a plurality of circuits. The circuit conductors are spaced on the pad, with each of the circuits defining a linear dimension across a respective pair of the circuit conductors. The linear dimension has a correlation to a predetermined liquid volume of an incontinent event desired to be detected. A controller applies voltage from a power source to and checks continuity of the spaced circuits and totals the circuits. The controller indicates to a care provider that an incontinent event has occurred at a certain minimum liquid volume.
