Base plate and sensor assembly of an ostomy system having a leakage sensor

A base plate for an ostomy system, the base plate comprising:

• an adhesive layer having a distal side and a proximal side, the proximal side being configured for attachment of the base plate to a skin surface of a user,
• a plurality of electrodes arranged entirely on the distal side of the adhesive layer;
• and
• a masking element arranged between the plurality of electrodes and the adhesive layer, the masking element comprising a plurality of openings, wherein each opening of the plurality of openings:
• exposes a portion of an electrode of the plurality of electrodes to define a corresponding sensor point;
• and
• the corresponding sensor point is configured to permit output to propagate through the sensor point opening and contact the electrode.

An ostomy system configured to estimate moisture content in an adhesive layer, comprising:

• a base plate comprising:
• the adhesive layer having a distal surface and a proximal surface, the proximal surface being configured for attachment of the base plate to the skin surface of a user;
• an electrode assembly disposed on the distal surface of the adhesive layer and comprising a plurality of electrodes;
• and
• a masking element between the plurality of electrodes and the adhesive layer, the masking element comprising a plurality of openings, wherein each opening of the plurality of openings:
• exposes a portion of an electrode of the plurality of electrodes to define a corresponding sensor point;
• and
• the corresponding sensor point is configured to permit output to propagate through the opening and contact the electrode;
• and
• a monitor device that is electrically couplable to the electrode assembly, the monitor device configured to:
• measure a parameter of the adhesive at a sensor point of the electrode assembly;
• and
• determine an estimated moisture content of the adhesive layer based on the parameter.
