Abstract: A top-gated graphene field effect transistor can be fabricated by forming a layer of graphene on a substrate, and applying an electrochemical deposition process to deposit a layer of dielectric polymer on the graphene layer. An electric potential between the graphene layer and a reference electrode is cycled between a lower potential and a higher potential. A top gate is formed above the polymer.

Abstract: Systems and methods are disclosed for an underground antenna structure for radiating through a dissipative medium, the antenna structure. The antenna structure includes a dielectric substrate, a feeding structure disposed on the substrate, and one or more electrical conductors. The one or more electrical conductors are disposed on the substrate, oriented, and buried within the dissipative medium.

Abstract: In some aspects, olfactory devices include a housing having a first inlet and a second inlet, an ambient air inlet cartridge defining a channel in fluid communication with the first inlet, and a position sensor. The ambient air inlet cartridge includes a first member defining a first orifice, and a second member moveable relative to the first member, the second member defining a second orifice, where a degree of overlap between the first orifice and the second orifice controls a flow capacity of the channel. The position sensor signals the degree of overlap between the first orifice and the second orifice.
