Ostomy leakage detection system

A sensing accessory for detecting leakage in a medical device, comprising:

• a sensor region including a center opening and a plurality of sensors arranged around the center opening, wherein the plurality of sensors comprises at least two substantially elliptical conductive traces substantially surrounding the center opening and at least two arc-shaped conductive traces, wherein the at least two substantially elliptical conductive traces include a first trace and a second trace, and the at least two arc-shaped conductive traces comprises a first arc trace and a second arc trace, wherein each of the two substantially elliptical conductive traces is arranged at a different radial distance from the center opening, and each of the at least two arc-shaped conductive traces is arranged in a different sector in the sensor region;
• a connector region comprising a plurality of connection points at terminal ends of the plurality of sensors configured for electrical connection to an external device, and
• a tail region extending between the sensor region and connector region, the tail region having an elongated body.
