1. A wound monitoring and/or therapy apparatus comprising:
a wound dressing comprising a substantially stretchable substrate including a wound facing side and a non-wound facing side opposite the wound facing side,
the wound facing side of the substrate supporting a plurality of electronic components and a plurality of electronic connections that connect at least some of the plurality of the electronic components,
a conformal coating covering at least the plurality of electronic components and the plurality of electronic connections, the conformal coating configured to prevent fluid from coming into contact with the plurality of electronic components and the plurality of electronic connections, and
a portion of the wound facing side of the substrate comprises a layer of material forming a first region that is substantially non-stretchable and that encloses an entire perimeter of at least one electronic component from the plurality of electronic components, wherein the first region is protected from strain applied to the substrate.
