Acousto-electronic gas sensors with layered structures

Abstract

The results of the development and investigation of acousto-electronic gas sensors with film structures are presented. Using the example of a sensor with a surface acoustic wave element and an adsorptive film of CH₃(CH₂)₁₇COONa deposited on the working surface of the waveguide by the Langmuir–Blodgett method, the possibility of creating intelligent sensors operating in real time is demonstrated. A distinctive and important advantage of these sensors compared to analogues is the absence of the need for heating during the adsorption–desorption stage.
