ABSTRACT:
A device for delivery of a powder to the skin of a subject includes a pad, made of an insulating material and having an upper side and a lower side, which lower side is placed against the skin after application of the powder thereto. An electrical power source applies an electrical potential to the pad, causing the powder to adhere by electrostatic force to the lower side of the pad, and then alters the potential so that the powder is released from the pad and contacts the skin against which the pad is placed.
