Zusammenfassung:	A sensor 10 for detecting gaseous agents has a transducer, which includes an electrical resonant circuit that forms an antenna 14. The sensor 10 further includes a sensing material 12 that is disposed on at least a portion of the transducer. The sensing material 12 is configured to simultaneously exhibit a capacitance response and a resistance response in the presence of a gaseous agent. The sensor 10 may be reversible, battery free, and may require no electrical contact with a sensor reader.
