a Schematic illustration of the testing equipment for sensitive characteristics of the sensor. b Sensitivity characteristics of the sensor. c Schematic illustration of the testing equipment for the response speed of the sensor. d Normalized response of the sensor to humid flow chopped at 4 Hz and estimated response time (2.76 ms) and recovery time (12.4 ms) of the sensor. t1 and t2 represent the times when the response rises to 10% and 90% of the stable value, respectively. t3 and t4 represent the times when the response drops to 90% and 10% of the stable value, respectively. e Normalized response of the sensor to humid flow chopped at 100 Hz and 300 Hz.
