Abstract
A wound dressing is disclosed. In examples, the wound dressing includes a first adhesive layer with a proximal surface configured for attachment of the wound dressing to the skin surface of a user, an absorbent core layer, an electrode assembly, and a top layer on a distal side of the electrode assembly. The electrode assembly includes a plurality of electrodes arranged on a distal side of the absorbent core layer and a plurality of sensor points distributed along a distal surface of the absorbent core layer.

A wound dressing comprising:
- a first adhesive layer with a proximal surface configured for attachment of the wound dressing to a skin surface of a user;
- an absorbent core layer;
- an electrode assembly comprising a plurality of electrodes arranged on a distal side of the absorbent core layer, the plurality of electrodes comprising a first set of first electrodes, the electrode assembly comprising a plurality of sensor points distributed along a distal surface of the absorbent core layer;
- a first masking layer arranged between at least a part of the electrode assembly and the first adhesive layer, wherein the first masking layer comprises a plurality of sensor point openings that each correspond to a sensor point of the electrode assembly, thereby permitting exudate to pass from the proximal surface of the first adhesive layer and through a respective sensor point opening of the masking layer to the sensor point of the electrode assembly;
- and
- a top layer on a distal side of the electrode assembly,
- wherein the electrode assembly comprises a first support layer, and wherein the first set of first electrodes is printed on the first support layer.
