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; andone 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. 2. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the substrate comprises: a flexible material. 3. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the transmission unit is configured to transmit the signal in response to an interrogation signal. 4. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the transmission unit comprises: a transmitter unit; anda receiver. 5. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the transmission unit comprises: a radio frequency identification (RFID) device. 6. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the transmission unit comprises: at least two antennas. 7. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the transmission unit comprises: a Near Field Communication (NFC) device. 8. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the hollow tubular projection comprises: a physical conduit configured for fluid flow from the interior region of the unpenetrated wound dressing to a location in contact with the transmission unit. 9. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the hollow tubular projection comprises: one or more additional sensors; andat least one substantially hollow enclosure substantially encircling the one or more additional sensors, the at least one substantially hollow enclosure including one or more openings within the enclosure distal to an attachment to the substrate. 10. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the one or more sensors are partially internal to the hollow tubular projection. 11. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the one or more sensors are configured to actuate a switch in the transmission unit in response to a stimulus. 12. The appurtenance to an unpenetrated wound dressing of claim 1, comprising: a connector between the transmission unit and the one or more sensors. 13. The appurtenance to an unpenetrated wound dressing of claim 1, comprising: an indicator operably attached to the transmission unit. 14. The appurtenance to an unpenetrated wound dressing of claim 1, wherein the hollow tubular projection has a curvilinear shape. 15. The appurtenance to an unpenetrated wound dressing of claim 14, wherein the tubular projection has a hook shape. 16. The appurtenance to an unpenetrated wound dressing of claim 1, further comprising another hollow tubular projection that is non-parallel relative to the hollow tubular projection. 17. The appurtenance to an unpenetrated wound dressing of claim 1, further comprising 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 hollow tubular projection. 18. The appurtenance to an unpenetrated wound dressing of claim 17, wherein the outer cover is configured to seal a juncture between the appurtenance and the 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; andan 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. 20. The appurtenance to an unpenetrated wound dressing of claim 19, wherein the barb-shaped feature is configured to bend during insertion into the wound dressing. 21. The appurtenance to an unpenetrated wound dressing of claim 19, wherein the projection is tubular. 22. The appurtenance to an unpenetrated wound dressing of claim 19, further comprising 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.
