In this letter, a WO3 nanoparticle gas sensor was fabricated using an ICP-assisted hot wire system. The results of experiments indicated that the sensitivity became smaller when the measured temperature increased. It was also found that the WO3 nanoparticle gas sensor prepared at an annealing temperature of 400 °C had the greatest sensitivity. The measured sensitivity for a micro-electromechanical system type WO3 nanoparticle gas sensor was found to be around 3.22, 3.91, 5.02, 7.52, 11.68, and 15.93 when the operating temperature of the micro-heater was 150 °C and the concentration of injected NO gas was 100, 150, 200, 250, 300, and 350 ppb, respectively.
