High power consumption due to the need for elevated operating temperature remains a challenge for metal-oxide gas sensors. This letter presents a tungsten-doped Nb2O5 nanorod sensor suitable for toxic and combustible gas monitoring applications. The fabricated prototype has been experimentally characterized for H2, CH4, and NO2 gases for both static and dynamic performances, under a wide range of bias currents and operating temperatures. Results indicate that the large surface-to-volume ratio of the nanostructured sensing film achieves strong responses even down to room temperature, which is highly advantageous for low-power, heater-free, portable sensing applications.
