Abstract: A gas sensor has a microstructure sensing element which comprises a plurality of interconnected units wherein the units are formed of connected graphene tubes. The graphene tubes may be formed by photo-initiating the polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice, removing unpolymerized monomer, coating the polymer microlattice with a metal, removing the polymer microlattice to leave a metal microlattice, depositing graphitic carbon on the metal microlattice, converting the graphitic carbon to graphene, and removing the metal microlattice.

Abstract: A pressure transducer includes a cavity, a first dipolar molecule disposed within the cavity, and a second dipolar molecule disposed within the cavity. The first dipolar molecule exhibits a quantum rotational state transition at a fixed frequency with respect to cavity pressure. The second dipolar molecule exhibits a quantum rotation state transition at a frequency that varies with cavity pressure.
