The opto-electrical cable core may include a wire, one or more channels extending longitudinally along the wire, and one or more optical fibers extending within each channel. The opto-electrical cable may be made by a method that includes providing a wire having a channel, providing optical fibers within the channel to form an opto-electrical cable core, and applying a polymer layer around the opto-electrical cable core. A multi-component cable may include one or more electrical conductor cables and one or more opto-electrical cables arranged in a coax, triad, quad configuration, or hepta configuration. Deformable polymer may surround the opto-electrical cables and electrical conductor cables.

Abstract: A self-bonding conductive wire and methods in which it is made and used. The wire comprises a conductor, an insulator, and a self-bonding outer coating. The self-bonding outer coating is a polyester polyether block copolymer. The insulator is an ethylene/tetrafluoroethylene copolymer, one or more layers of which may be used to insulate the conductor. The self-bonding capabilities of the wire may be activated by heating the wire, causing the outer coating to thermoplastically deform and fuse, allowing for the creation of self-supporting structures such as large bobbin-less coils. The use of the polyester polyether block copolymer for the self-bonding outer coating is superior to other materials, in which significant degradation of qualitative properties following self-bonding is observed, resulting in a superior self-bonding conductive wire.

Abstract: A busbar includes: an elongated busbar body which is composed of an electrically conductive material; and an insulating coating which covers the circumference of the busbar body. The cross section of the busbar body orthogonal to the longitudinal direction is substantially rectangular. The insulating coating is composed of a light curing resin which has an elongation percentage of not less than 50% after being cured and a Young's modulus of not more than 900 MPa. And the insulating coating is formed by applying the light curing resin onto the surface of the busbar body and then curing the applied light curing resin. The light curing resin has a viscosity of 10 to 1000 Pa·s at 25° C.

Abstract: In a method for printing a three dimensional structure, a continuous length of fiber that includes, interior to a surface of the fiber, a plurality of different materials arranged as an in-fiber functional domain, with at least two electrical conductors disposed in the functional domain in electrical contact with at least one functional domain material, is dispensed through a single heated nozzle. After sections of the length of fiber are dispensed from the heated nozzle, the sections are fused together in an arrangement of a three dimensional structure. The structure can thereby include a continuous length of fiber of least three different materials arranged as an in-fiber functional device, with the continuous length of fiber disposed as a plurality of fiber sections that are each in a state of material fusion with another fiber section in a spatial arrangement of the structure.
