Abstract: In some embodiments, transfer print circuits and associated fabrication methods are provided. In some embodiments, some transfer print circuits include a graphene sheet-based conductive composition printed on at least a portion of a first layer. A second layer is in communication with at least a portion of the first layer in a manner that at least covers a portion of the graphene sheet-based conductive composition. An electrical device is in electronic communication with the graphene sheet-based conductive composition. The graphene sheet-based conductive composition includes graphene sheets having an interconnectivity and a horizontal alignment.

Abstract: Embodiments of the present invention relate to graphene-based microphone diaphragms. In one embodiment, a acoustic wave sensor comprises a diaphragm comprised of a graphene-based composition, wherein the diaphragm has a first side at least partially covered with a reflective material. An emitter fiber is positioned proximate to the diaphragm, wherein the emitter fiber transmits light towards the first side. A collector fiber is positioned proximate to the diaphragm, wherein the collector fiber captures at least a portion of light reflected by the first side, wherein the collector fiber is in communication with a detector. A converter is in communication with the detector and converts a signal received by the detector to a digital signal for processing. The portion of light that is captured as a result of diaphragm distortion is different than the portion of light captured in the absence of diaphragm distortion. The graphene-based composition includes graphene sheets.
