15. A sensor patch for attachment to a base plate of an ostomy appliance, the sensor patch comprising:
a first adhesive layer with a proximal side configured for attachment of the sensor patch to the skin surface of a user, the first adhesive layer having a stomal opening, and
a sensor assembly, the sensor assembly comprising:
a support layer, and
a planar electrode assembly arranged on a surface of the support layer, the electrode assembly comprising at least a first electrode;
wherein the first electrode comprises a first main branch extending along a first main path and a first plurality of subbranches connected to the first main branch, the first plurality of subbranches including a first primary subbranch and a first secondary subbranch, wherein the first primary subbranch is connected to the first main branch at a first primary connection point and extending in a first primary direction at a first primary angle relative to a tangent to the first main path at the first primary connection point, and
wherein the first secondary subbranch is connected to the first main branch at a first secondary connection point and extending in a first secondary direction at a first secondary angle relative to a tangent to the first main path at the first secondary connection point, and
wherein the first primary subbranch and the first secondary subbranch are symmetrical about a line of symmetry parallel with the first primary direction and the first secondary direction, respectively, and
wherein the electrode assembly of the sensor assembly is arranged between a distal side of the first adhesive layer and the support layer of the sensor assembly.
