Abstract
A wound covering includes chemical sensor within a detecting temperature and pH at the skin surface. Changes in temperature and changes in pH at the wound surface are communicated by providing modifications to the visual indicia. The combination of either a change in temperature, a change in pH, or both provide a changing visual indicium that can communicate to the bandage wearer, or a medical caregiver, that a need to change the dressing and/or treating of the wound is in order. The visual indicia may be expressed as a change in color, or a change in the shade of a color that is located at or transmitted to the outer surface of the wound covering. The condition of a wound may be determined without the need to undress the wound for visual inspection.
