However, the wound dressing of Figure 26 includes an additional masking or obscuring layer 1208 positioned above the dressing layers and below the cover layer 1210. As illustrated in Figure 26, the wound dressing layers can include an absorbent area 1260 and an electronics area 1261. In some embodiments, the electronics area 1261 can include the electronics unit 1204.
  • the masking or obscuring layer can span the entire length of the absorbent area 1260 and electronics area 1261. In some embodiments, the masking or obscuring layer can have a larger perimeter than the spacer layer, absorbent layer, and electronics unit, cradle, or cassette and can overborder the absorbent material and electronics unit, cradle, or cassette as shown in Figure 26.
  • the absorbent components and electronics components can be overlapping but offset.
  • a portion of the electronics area can overlap the absorbent area, for example overlapping the superabsorber layer, but the electronics area is not completely over the absorbent area. Therefore, a portion of the electronics area can be offset from the absorbent area and only provided over the cushioning spacer layers.
  • Conditional language such as “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements, or steps.
