Piezoelectric Resonators for Gas Sensing Applications

Popis výsledku v původním jazyce

This study deals with acoustic resonators, versatile piezoelectric devices capable of studying adsorption of molecules down to the picogram regime. Acoustic resonators can be generally classified into two frequent groups which are Thickness Shear Mode (TSM) resonators (also commonly called as Quartz Crystal Microbalances ? QCMs) and Surface Acoustic Wave (SAW) devices. Both have been extensively used in the field of gas sensing as they are relatively easy to fabricate, robust and extremely sensitive. The main applica-tion of acoustic resonators is in time and frequency control. However, the resonance frequency depends on the resonator?s environment and can therefore be used as a frequency-based sensor in large applications scale. The focus of this study lies on TSM resonators, since this class of piezoelectric devices is the most frequently used in physical and chemical sensor and biosensor applications, and they are largely commercially available. The study is divided into three parts
