    Abstract: A transponder comprises a first polymer layer. A radio frequency (“RF”) transponder is affixed to the first polymer layer, wherein the RF transponder includes a processor in electrical communication with a graphene-based antenna. A second polymer layer is formed on the first polymer layer and the RF transponder. The first polymer layer and second polymer layer form an encasement around the RF transponder. The encasement has a hermeticity of about 10−7 to about 10−12 atm·cc/sec. The encasement provides improved impact, temperature, vibration, chemical, and/or corrosion protection to the RF transponder.

In some embodiments, apparatus for monitoring surfaces of vessels and may include a substrate disposed proximate to the surface. By one approach, a Wheatstone bridge circuit is affixed to the substrate and comprises a sampling resistor configured to undergo a predetermined binding event. The sampling resistor comprises a conductive composition that includes fully exfoliated single sheets of graphene and is configured to undergo a conductivity change as a result of the predetermined binding event. The conductivity change corresponds to a change in an ambient environment of the surface. The sampling resistor is configured to undergo a resistivity change as a result of the predetermined binding event. The apparatus is configured to be disposed proximate to the surface.

    Abstract: The present invention relates generally to transmission lines and specifically to textile transmission line assemblies. The textile transmission line assemblies are capable of lateral bending, axial rotation, and stretching without suffering from a statistically significant loss of its performance characteristics. Antenna elements are incorporated with the textile transmission line assemblies (hereinafter “combination assemblies”). The textile transmission line assemblies can be incorporated in to garments, apparel items, bags, tents, or other textile-based objects. The textile transmission line assemblies are configured to be flexibly affixed to textile items. The textile transmission line assemblies are impact resistant. Wearable communications systems that incorporate at least one textile transmission line assembly and/or combination assembly are also disclosed.

    Abstract: The instant disclosure relates to EMI shielding structures. A conductive composition is formed that includes a polymer and graphene present as a 3D-matrix therein. Rectangular EMI shielding panels are formed using the composition. Rectangular EMI shielding panels are affixed orthogonal to each other. The EMI shielding panels are successively overlapped to form a plurality of interconnected EMI shielding planes. The EMI shielding panels are affixed to each other to form a helical EMI shielding structure that folds and unfolds along its center axis. The EMI shielding planes are angularly offset from each other about the center axis to form a helical structure when in the unfolded state. The EMI shielding panels include an encapsulating layer and/or metallic layer. The EMI shielding planes rotate about the center axis when the HES structure transitions between the folded and unfolded states.

    Abstract: A chaff electronic countermeasure device that includes an antenna element positioned on a substrate and in electrical communication with an integrated circuit. The conductive antenna element includes a conductive composition of a conductive polymer and graphene sheets. The device absorbs from a radar source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device reradiates at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude. The device is configured to be dispersed from a mobile platform. The device is configured to reradiate at least a second radio frequency toward the radar source, thereby resulting in an increased radar cross section of the device as perceived by the radar source
