Implementations of a battery pack with reduced magnetic field emission are provided. The battery pack is configured to reduce or eliminate the magnetic field normally generated while electrical current is being drawn from cylindrical-steel electrochemical cells (e.g., AA batteries) by a connected electrical device. In some implementations, a battery pack with reduced magnetic field emission comprises two or more electrochemical cells positioned in a coaxial configuration. In this coaxial configuration, the supply path is through the center of each electrochemical cell, and the return path is through a conductive sleeve positioned about each electrochemical cell of the battery pack. In this way, the supply path and the return path are as close as is physically possible, thereby minimizing any magnetic field generated between the conductors (i.e., between the electrochemical cells and their conductive sleeves). An insulating layer of material separates each cylindrical-steel electrochemical cell from the conductive sleeve positioned thereabout.

In various embodiments, the present invention is directed to polymer based heat dissipating materials and films that are highly elastic, thermally conductive and optically transparent and made using a non-conventional approach. The polymer based heat dissipating materials and films of the present invention use a hybrid filler comprising a very small loading of traditional fillers like boron nitride or graphene oxide combined with non-conventional fillers like organic linkers, dispersed in a preferably non-conductive polymer matrix. These hybrid fillers provide an elastic thermal network that drives heat conduction across the polymer chains, while provided flexibility and optical clarity.

Systems and methods presented herein provide for elastomeric and flexible cables. In one embodiment, the cables are configured with elastomeric cabling and circuitry. For example, a flexible circuit line (or lines) may be wrapped about an extruded elastomeric substrate (e.g., a polymer). Integrated circuits (e.g., sensors, accelerometers, light emitting diodes, controllers, microprocessors, etc.) may be disposed at various points along the circuit line(s). The cable may then be wrapped with a Polytetrafluoroethylene (PTFE) tape than can be heated to shrink about the cable for protection of the underlying circuitry. Then, the cable may be surrounded with a layer of polymer and extruded to form an elastomeric and flexible cable.

A flex flat cable (FFC) structure includes metallic transmission wires arranged in parallel, first insulating jackets, and second insulating jacket. The metallic transmission wires includes one or more power wires and signal wires. The power wire is configured to transmit power. The signal wires are configured to transmit a data signal. Each of first insulating jackets encloses one of metallic transmission wires. The second insulating jacket surrounds the first insulating jackets. An embossment pattern is arranged on an external surface of the second insulating jacket. The embossment pattern includes meander lines in a top-view direction and in an extending direction for the metallic transmission wires. The meander lines are not arranged parallel.

Yarns for electrical conduction that comprise a composite of fibres composed of carbon nanotubes and/or of a multiplicity of graphene layers and have a specific porosity are already known. The yarns have an electrical insulation layer, which is produced by application of a polymer coating. The electrical insulation layer has to adhere to the yarn sufficiently well for the insulation not to detach even in the event of mechanical stress, for example deflection with a small bending radius. Furthermore, the electrical insulation layer should be as thin as possible in order to achieve a low thermal resistance. Additionally, the electrical insulation layer has to be elastic enough to be able to cope with any geometric changes in the non-rigid yarn without detaching. In the electric conductor according to the invention, the electrical insulation is improved. The invention provides for the outer fibres of the composite to be fluorinated in such a way that they form an electrical insulation layer (2) and for the fibres in an internal region (3) to be electrically conductive.
