Abstract :
In this paper different topologies of CNT-based RF passive gas sensors are presented, particularly focusing on wireless transducers, which can directly indicate gas concentration through the change of easy to-monitor RF parameters. CNTs feature numerous unique properties that could potentially enable the next generation of gas sensors with sensitivities better by 1-2 orders of magnitude with respect to existing ones.
