Patent ID: 7457667

Claim:
A wound dressing comprising: a primary surface of a pliable dressing material, wherein the pliable dressing material is adapted to be applied to an area of damaged tissue; a first design formed from a first ink that includes a mixture of a polymer and a first element, the first ink being printed into a position of contact with the primary surface, the first element including a metal species, and the first design including at least one dot, wherein selective ones of the at least one dot have approximately a 1.5 mm+/− 1 mm mean diameter; a second design formed from a second ink that includes a mixture of a polymer and a second element, the second element including a different metal species than the first element, the second ink being printed into a position of contact with the primary surface, and the second design including at least one other dot, wherein selective ones of the at least one other dot have approximately a 2.5 mm+− 2 mm mean diameter; a spacing on the primary surface that is between the first design and the second design such that the first design does not physically contact the second design, wherein the spacing is approximately 1.5 mm+− 1 mm; and at least one repetition of the first design and the second design, the at least one repetition of the first design being substantially adjacent the second design, wherein the at least one repetition of the first design and the second design, in conjunction with the spacing between the first design and the second design, defines at least one pattern of at least one voltaic cell for spontaneously generating at least one electrical current when introduced to an electrolytic solution.
