Wound dressing with electrode multiplexing and related methods

A wound dressing comprising:

• a first adhesive layer comprising a proximal surface configured for attachment of the wound dressing to a skin surface of a user;
• an electrode assembly comprising a plurality of electrodes including a first set of first electrodes;
• a monitor interface for forming a mechanical and electrical connection with a monitor device, the monitor interface comprising a coupling part and a plurality of terminals including a first terminal;
• and
• a multiplexer comprising a number of N input pins and a number of M output pins, wherein the N input pins include a first set of first input pins for connection to first electrodes of the first set of first electrodes, the first set of first pins including a first primary input pin and a first secondary input pin, and the M output pins include a first output pin,
• wherein the first primary input pin is connected to a first primary electrode of the first set of first electrodes and the first secondary input pin is connected to a first secondary electrode of the first set of first electrodes, and the first output pin is connected to the first terminal of the monitor interface, and
• wherein the multiplexer is configured to select a multiplexer configuration from a set of multiplexer configurations based on a control signal received via a control pin of the monitor interface, the set of multiplexer configurations comprising:
• a first multiplexer configuration where the first primary input pin is connected to the first output pin;
• and
• a second multiplexer configuration where the first secondary input pin is connected to the first output pin.
