摘要： Embodiments of the present invention relate to transponder fabrication. In an embodiment, a plurality of antenna elements is applied to a first substrate at a first pitch. A plurality of fully functioning first transponders is positioned on to the first substrate in a manner to each be in electrical communication with an antenna element included in the plurality of antenna elements and thereby forms a plurality of fully functioning second transponders. The plurality of fully functioning first transponders are positioned on a second substrate at a second pitch. The plurality of fully functioning first transponders have a first read range. Second transponders have an increased read range relative to second transponders. The second pitch is greater than the first pitch.

摘要： 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.

摘要： 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.
