Abstract

An ostomy device includes a proximal side configured for attachment to a user, a distal side opposite to the proximal side, and a leakage detection sensor having electrically conductive circuitry supported on a support layer. The leakage detection sensor is configured to detect ostomy effluent by detecting a change in resistance in the electrically conductive circuitry. The ostomy device may be an ostomy appliance or an ostomy accessory.
