Pressure Wounds (IMAGE) University of California - Berkeley Caption Researchers varied the amount of pressure applied to the skin, creating bedsores ranging in severity. The orange hexagon marks where the bandage was placed on the skin, and the dotted blue circle highlights where pressure was applied to the tissue. The "reversible damage" example highlights sensitivity of the "smart bandage" impedance sensor since the wound is not visible at the surface of the skin.
