| Abstract | A surface acoustic wave (SAW) gas sensor with carbon nanotubes (CNTs) layered films as interactive nanomaterial is presented. A SAW twoport integrated on ST-cut quartz substrate has been characterized as oscillator in dual differential mode the resonant frequency of 433.92 and 915 MHz. layers based on filler of CNTs, grown by RFplasma chemical vapor deposition, have been prepared the Langmuir-Blodgett (LB) technique to coat the SAW for organic vapor detection, at room temperature. concerning the SAW sensing performance towards , methanol, acetone, m-xylene, and toluene are described. results demonstrate clearly the potential of the SAW nanocomposite chemical microsensors at high frequencies the fabrication of low-cost and highly gas-sensitive devices for room-temperature sensing operations. ©2008 IEEE. |
