Abstract: Graphene printing is disclosed. A disclosed example graphene printing apparatus includes a gas source to cause a graphene precursor gas to flow across a surface of a substrate, and a localized heat source to locally heat portions of the surface to cause graphene to grow at the portions of the surface based on a printing pattern.

Abstract: Examples disclosed herein relate to a layered RFID tag. In one implementation, a layered passive chipless RFID tag includes a first conductive layer, a second dielectric layer, and a third conductive layer. The first, second, and third layers may be in a stacked configuration with the second layer between the first layer and the second layer.

Abstract: In an example implementation, a substance detection device includes a chamber with chamber walls, a chamber top, and a chamber bottom. A substrate comprises imprinted nanostructures positioned within the chamber, and the substrate is coupled to the chamber walls to form the chamber bottom. An inert gas is sealed within the chamber.
