Chemiresistive gas sensors with low power consumption, fast response, and reliable
fabrication process for a specific target gas have been now created for many applications …

We report ZnO/glass surface acoustic wave (SAW) humidity sensors with high sensitivity and
fast response using graphene oxide sensing layer. The frequency shift of the sensors is …

MIL-101 (Cr) films were deposited on the quartz crystal microbalance and interdigitated
electrode transductors as humidity sensors. Both devices combine high sensitivity with fast …

The sensing property and mechanism of surface acoustic wave (SAW) humidity sensors
based on sol–gel SiO 2 films were investigated. The SiO 2 films were fabricated with a sol …
