Opening claim text (preview).
The invention claimed is: 1. A composite conductor comprising: an elongate support having (i) an outer surface comprising a whisker forming metallic layer, and (ii) a non-circular cross-section; and a carbon nanotube yarn intertwined with the elongate support, wherein the yarn is infiltrated by self-assembled whiskers from the whisker forming metallic layer. 2. The composite conductor of claim 1 , wherein the elongate support is selected from the group consisting of copper, tin, aluminum, silver, gold, nickel, palladium, iron, their respective alloys, and combinations thereof. 3. The composite conductor of claim 1 , wherein the whisker forming metallic is an outer coating of the elongate support. 4. The composite conductor of claim 1 , wherein the whisker forming metallic is selected from the group consisting of tin, indium, gallium, and combinations thereof. 5. The composite conductor of claim 1 , wherein the elongate support is a central core about which the carbon nanotube yarn is wrapped. 6. The composite conductor of claim 1 , wherein the elongate support is eccentric with respect to an axis of the composite conductor. 7. The composite conductor of claim 1 , further comprising a first end terminated in a terminal, the terminal comprising an outer layer of a whisker forming metallic. 8. The composite conductor of claim 1 wherein the elongate support having an outer surface comprising a whisker forming metallic comprises a tin-coated copper wire, the wire having a non-circular cross-section. 9. The composite conductor of claim 1 , wherein the elongate conductor has a cross-section in which a longest dimension is in the range of 1 micron to 1 millimeter. 10. The composite conductor of claim 1 further comprising an outer jacket overlying the intertwined elongate support and carbon nanotube yarn. 11. The composite conductor of claim 10 , wherein the outer jacket comprises an insulating polymeric material. 12. A composite conductor comprising: an elongate metallic support forming a conductor core and having (i) an outer surface comprising a whisker-forming metallic coating, and (ii) a non-circular cross-section; and a carbon nanotube yarn intertwined with the elongate support, wherein the yarn is infiltrated by self-assembled whiskers from the whisker-forming metallic coating. 13. The composite conductor of claim 12 , wherein the whisker-forming metallic coating is selected from the group consisting of tin, indium, gallium, combinations thereof and whisker-forming alloys thereof. 14. The composite conductor of claim 13 , wherein the elongate support is a wire selected from the group consisting of copper, tin, aluminum, silver, gold, nickel, palladium, iron, their respective alloys, and combinations thereof. 15. The composite conductor of claim 14 , wherein the elongate support is a solid conductor. 16. The composite conductor of claim 12 , wherein the non-circular cross-section has a longest dimension in the range of 1 micron to about 1 millimeter. 17. A terminated connection comprising a conductor comprising an elongate support (i) having a non-circular cross-section, and (ii) comprising a carbon nanotube yarn; and a conductive terminal comprising a whisker-forming metallic coating secured to the conductor, wherein the conductor is infiltrated by a plurality of self-assembled whiskers extending from the terminal. 18. The terminated connection of claim 17 , wherein the elongate support comprises a whisker forming metallic intertwined with the carbon nanotube yarn. 19. The terminated connection of claim 17 , wherein the whisker-forming metallic coating comprises tin, indium, gallium, or whisker-forming alloys thereof.
