Nov 15, 2023 · This work is intended to design a multilayered SAW structure that exhibits the utilization of CNT material as a sensing layer with an organic polymer PIB on a LiNbO 3 piezoelectric substrate in a SAW-based one-port resonator.

Surface acoustic wave (SAW) gas sensors based on the use of carbon nanotube (CNT) networks as sensitive layers have been investigated for the detection of atmospheric gas pollutants: volatile organic compounds (VOCs), NO 2, CO, and H 2. SAW sensor configuration consists of a delay line made on a piezoelectric substrate (ST -X cut quartz) and a ...
