Abstract
Abstract An electrically conductive textile fabric in which the electrical conductivity may be made to vary in a pattern configuration, and a method for manufacturing such fabric. A textile fabric is coated with an electrically conductive polymeric coating, and the coating is selectively removed in those areas in which a reduced electrical conductivity is desired. The removal may be achieved by means of high velocity water jets, sculpturing, or other means.
