The preferred embodiment utilizes metal coated high strain fabric reinforcement including but not limited to fiberglass, cotton fiber, or other materials that can undergo deformation, and various resin or elastomer compounds to create a conductive polymer whose resistivity and resistance remain essentially constant under a strain of approximately 0-150% or more. Additionally, the preferred embodiment utilizes a method of imprinting, depositing, etching, or embossing a design or pattern of conductive metal on fabric used in composites. The use of designs of conductive metals wrapped around a deformable core and the unique features of elastomeric polymers allows for their use as a flexible circuit board, formable heaters, and other various uses.
