A wound dressing that provides galvanic current and has antimicrobial properties. The dressing comprises a pliable base material, along with a pattern of deposited metal flakes. The metal flakes include at least two different metal types which are deposited in patterns which touch or overlap, typically in a repeating pattern. The two metals create a galvanic current in the wound area. The metals are deposited in mounds so that the wound dressing continues to work over extended periods of time.
