Abstract
Thin conductive metal coatings suitable for flexible nonmetal fine wires and leads are described. Polymer clad silica fiber cores are produced by plasma coating with single or dual layers of metals such as silver, gold or titanium to provide micro thin leads such as those used for pacemakers and fracture resistant aircraft wires that are both conductive and resistant to flexing breakage. The metal surfaces can be used to transmit analog signals while the nonmetal cores can be designed to transmit digital signals. Select deposition conditions can produce nanorough metal coating surfaces which promote cell adhesion so that tissue scarring in vivo is greatly reduced.
