ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers
نویسندگان
چکیده
We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used for the attachment of a sensitizing layer. Data is presented for the rigid and viscous loading, which indicates a small reduction in mass sensitivity compared to a Love wave device. Biosensing capabilities of these discontinuous 'sectional' guiding layer devices are demonstrated using protein adsorption from solution.

Theoretical mass, liquid, and polymer sensitivity of acoustic wave sensors with viscoelastic guiding layers
The theoretical sensitivity of Love wave and layer-guided shear horizontal acoustic plate mode ~SH-APM! sensors for viscoelastic guiding layers and general loading by viscoelastic materials is developed. A dispersion equation previously derived for a system of three rigidly coupled elastic mass layers is modified so that the second and third layers can be viscoelastic. The inclusion of viscoela...

Using a seed layer-free hydrothermal method, ZnO nanorods (NRs) were deposited on ST-cut quartz surface acoustic wave (SAW) devices for ammonia sensing at room temperature. For a comparison, a ZnO film layer with a thickness of 30 nm was also coated onto an ST-cut quartz SAW device using a sol-gel and spin-coating technique. The ammonia sensing results showed that the sensitivity, repeatability...
متن کاملTheoretical mass sensitivity of Love wave and layer guided acoustic plate mode sensors
A model for the mass sensitivity of Love wave and layer guided shear horizontal acoustic plate mode ~SH–APM! sensors is developed by considering the propagation of shear horizontally polarized acoustic waves in a three layer system. A dispersion equation is derived for this three layer system and this is shown to contain the dispersion equation for the two layer system of the substrate and the ...
متن کاملSurface Acoustic Wave Ammonia Sensors Based on ST-cut Quartz under Periodic Al Structure
Surface acoustic wave (SAW) devices are key components for sensing applications. SAW propagation under a periodic grating was investigated in this work. The theoretical method used here is the space harmonic method. We also applied the results of SAW propagation studied in this work to design a two-port resonator with an Al grating on ST-cut quartz. The measured frequency responses of the reson...
