    Abstract: Embodiments of the present invention relate to microphones diaphragms. In one embodiment, a sensor comprising a diaphragm comprised of a composition having a plurality of individual graphene sheets. An emitter formed in a manner to transmit lights towards a surface of the diaphragm. A collector that captures at least a portion of light that is reflected by the diaphragm. A converter is in communication with the detector that converts a signal that is generated by the sensor to a digital signal for processing. The graphene-based composition includes graphene sheets.

    Abstract: Generally speaking, pursuant to various embodiments, interconnect apparatuses are provided herein to couple flexible circuits to control circuits. In some embodiments, the apparatus can include a first portion housing one or more control circuits and a second portion conductively coupled to a flexible circuit. In some embodiments, the first portion may be configured to be coupled to the second portion such that the control circuit can be conductively coupled to the flexible circuit when the first portion is coupled to the second portion. In some embodiments, the control circuit can be configured to capture temperature readings. In some embodiments, the control circuit can be configured to capture proximity readings. In some embodiments, the control circuit can be configured to include one or more communications devices.

    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.

    Abstract: Embodiments of the present invention relate to graphene-based Rotman lenses. In an embodiment, a lens is formed on a surface of a dielectric plate. The lens comprises a composition having individual sheets of graphene. The lens includes a plurality of first transmission lines extending from a first lens contour and a plurality of second transmission lines extending from a second lens contour. The plurality of first transmission lines each terminate at a first port. The plurality of second transmission lines each terminate at a second port. The first contour and the second contour are positioned opposite each other. The first port and/or the second port has a width of λ/2 or less. The individual graphene sheets form a three-dimensional interconnected network within the composition.
