Enhancing chemical identification efficiency by SAW sensor transients through a data enrichment and information fusion strategy—a simulation study
Prashant Singh,R. D. S. Yadava +1 more
TL;DR: In this paper, the authors proposed a new approach for improving the odor recognition efficiency of a surface acoustic wave (SAW) transient sensor system based on a single polymer coating, where the vapor identity information is hidden in transient response shapes through dependences on specific vapor solvation and diffusion parameters in the polymer coating.

Theoretical and Experimental Identification of Love Wave Frequency Peaks in Layered Structure ZnO/Quartz SAW Device
TL;DR: In this paper, the authors investigated the layered structure ZnO/Quartz (90deg rotated ST-cut) theoretically and experimentally and identified the generated waves and their higher modes in this structure except the mode 0 that shows comparable velocity for both Rayleigh and Love waves.

A diffusion limited sorption–desorption noise model for polymer coated SAW chemical sensors
R. D. S. Yadava,Vivek K. Verma +1 more
TL;DR: In this paper, the authors present a new model for the sorption-desorption noise in polymer-coated SAW chemical sensors, which visualizes the change in free energy associated with the partitioning of analytes from the vapor phase into the polymer coating as the activation energy for both the adsorption and desorption processes.
