Interconnects—Graphene Signal Cables

(12) Signal cables made from nanocomposite material consist of three basic elements: two plugs 1, 2, connected with a connecting part (FIG. 1). The main element of the connecting portion is flexible nanocomposite material 3.

(13) Flexible nanocomposite material 3 is a heterogeneous material structure composed of two or more components with different properties. The properties of the composites are not the sum or average of the properties of its components, and the material used 3 in its construction exhibits anisotropy of physical properties.

(16) The properties of graphene meet the conditions to create a nanocomposite material, which is the major component of the interconnects. One should, however, take into account manufacturing of interconnects of the nanocomposite material with nanostructures with properties similar to graphene.

(17) Referring to FIGS. 2A through 2D, signal cable of nanocomposite material layer 3 can be made in one of the following ways: a layer of graphene (G) (two-dimensional or 3D structure e.g. nanotubes) “embedded” on the surface of a single layer of polymer (P) (FIG. 2B); a layer of graphene (G) (two-dimensional or of a structure e.g. nanotubes) between the two polymer layers with contact leads to the surface of one of the two polymer layers (P) (FIG. 2A); a doped layer of graphene (DG) (two-dimensional or of a structure e.g. nanotubes) exists between the two polymer layers (P) with contact leads to the surface of one of the two polymer layers (FIG. 2C); a doped layer of graphene (DG) (two-dimensional or of a structure e.g. nanotubes) “embedded” on the surface of a single layer of polymer (P) (FIG. 2D).

(18) Use of graphene interconnects provides for the application of different plugs, depending on the standards used in different geographic areas.

(19) The length of the graphene interconnects is not limited by technical requirements, but only user's needs.

The Principle of Operation of Graphene Interconnects

(20) In general, interconnects are used for signal transmission, which is the process of transferring any messages or data between the transmitter (sender) and the receiver (the receiver), recorded in a specific code understood by both, and over a certain route.

(21) Signal source can be any measurable size changing in time, generated by natural phenomena or systems and converted into electricity. As all phenomena, the signal can be described using a mathematical apparatus, e.g. by entering a time-dependent function. We say that a signal carries information or allows the flow of information.

(22) Referring to FIG. 3, when the transmitter 5 is connected to the receiver 6 by means of terminals 1, 2 suitable for the devices (transmitter and receiver), and starting of the transmitter 5, the signal is transmitted via the interconnect 3 to the receiver 6 (FIG. 3).

(23) Depending on the design, the arrangement of graphene nanocomposite structure may take any form that can achieve maximum performance of the interface during its use.

(24) Referring to FIGS. 4 and 5, graphene interconnects, as regards the formation of the graphene layer 4 disposed on the polymer layer, can be symmetrical or asymmetrical, with flat or round cross-section. The method of laying the conductive graphene layer 4 is not mandatory, but dependent on the technical requirements for connecting the receiver 5 to the transmitter 6 (FIG. 5). The graphene layer 3 must be electrically connected to both plugs 1 and 2.

Advantages of this Invention

(25) Signal cables made from the nanocomposite material are resistant to: moisture and condensation splashing water-damage corrosion ultraviolet dust changes in the magnetic and the electromagnetic field changes in temperature in the range −40° C. to +70° C. ensuring accurate transmitter output signal at the receiver input.

(26) The invention can be used both in commercial equipment, as well as in specialized research equipment that requires high performance signal transmission, affecting the final result of the measurement.
