A surface acoustic wave (SAW) gas sensor with multiwalled carbon nanotubes (CNTs) layered films as chemically interactive nanomaterial is presented. A SAW two-port resonator integrated on ST-cut quartz substrate has been functionally characterized as oscillator in dual differential mode at the resonant frequency of 433.92 and 915 MHz. Nanocomposite layers based on filler of CNTs, grown by RF-plasma...
In this paper we report on Surface Acoustic Wave (SAW) gas sensors based on quartz two-port resonators configured as oscillators at resonant frequency of 915 MHz. Nanowires (NW) of semiconducting tin dioxide (SnO2) have been grown by Vapor Phase (VP) process and used as filler in a nanocomposite layer to fabricate a highly-sensitive nanomaterial for gas detection, at room temperature. The nanocomposite...
