ShearHorizontal Surface Acoustic WaveSensors BasedonPolyaniline forAmmoniaGasSensing (original) (raw)

This paper discusses the development and application of Shear-Horizontal Surface Acoustic Wave (SH-SAW) sensors based on polyaniline for ammonia gas sensing. SH-SAW technology enables sensitive detection of various gases due to its ability to respond to changes in the properties of the adjacent liquid or gas, making it suitable for environmental monitoring and safety applications. The paper explores the mechanistic aspects of SH-SAW, including how mechanical and electrical interactions affect sensor performance, as well as providing experimental results and sensitivity analysis.
