Abstract
A sensor device for identifying an ostomy effluent leak location in an ostomy system includes a stoma opening and electrically conductive circuitry arranged in pattern around the stoma opening. The electrically conductive circuitry includes a first electrode and a second electrode spaced from the first electrode. The first electrode is subdivided by a plurality of resistors spaced along a length of the first electrode. The second electrode extends as a continuous strip of conductive material. The sensor device is configured to detect electrical resistance in the electrically conductive circuit and identify a location of a leak based on the detected electrical resistance.
