Tonight I decided to attempt to splice together 2 electrodes used in a TENS (Transcutaneous Electrical Nerve Stimulator) unit. When I cut the molded connector from one of the lead wires, I discovered that, rather than being metallic, the stranded wire is composed of a bundle of dozens of ultra-fine, plastic-looking fibers within a pretty typical non-conductive sheath. About half of them appeared to be white, the other half black. And they were not intermingled. A cross section would show one side of the bundle is black fibers, the other white. Strange.
Wondering how this was electrically connected within the connector, I dissected it with an X-acto. The copper conductor is crimped to this bundle of fibers. Obviously, I will not be able to solder two of these wires together.
Does anyone know what this conductive material is and why it might be used in place of copper?
