1. An appurtenance to an unpenetrated wound dressing, comprising:
- a substrate configured to mechanically or chemically attach to the unpenetrated wound dressing;
a transmission unit attached to a surface of the substrate, the transmission unit including circuitry and at least one antenna, the transmission unit configured to transmit a signal;
a hollow tubular projection operably attached to the transmission unit, the hollow tubular projection having an exterior wall defining a channel, the exterior wall being of a size and shape to penetrate the unpenetrated wound dressing and extend into an interior region of the unpenetrated wound dressing and configured to sample a fluid associated with a wound, wherein a portion of the exterior wall of the hollow tubular projection configured to penetrate the unpenetrated wound dressing is oriented at an obtuse or acute angle relative to the substrate; and
one or more sensors disposed in a portion of the hollow tubular projection that is configured to penetrate the unpenetrated wound dressing, wherein the one or more sensors are configured to detect one or more characteristics of the unpenetrated wound dressing or an individual using the unpenetrated wound dressing.

19. An appurtenance to an unpenetrated wound dressing, comprising:
-
a substrate configured to mechanically or chemically attach to the wound dressing;
a transmission unit attached to a surface of the substrate, the transmission unit including circuitry and at least one antenna, the transmission unit configured to transmit a signal;a projection configured to be attached to the transmission unit and having a barb-shaped feature extending outward from the projection an acute angle, and configured to secure the appurtenance to the wound dressing, the projection of a size and shape to extend into an interior region of the unpenetrated wound dressing and configured to sample a fluid associated with a wound, wherein a portion of the projection that is configured to extend into an interior region of the unpenetrated wound dressing is oriented at an obtuse or acute angle relative to the substrate; and an outer cover configured to be attached to the substrate and to the unpenetrated wound dressing, wherein the outer cover is configured to be attached to a portion of the substrate at or near the projection. - View Dependent Claims (20, 21, 22)
