This study enhances shear-horizontal surface acoustic wave (SHSAW) device design for biosensing by developing a new model for guiding electrodes. This model improves the efficiency of SHSAW generation, crucial for accurate liquid-phase sensing applications.

Area of Science:

Acoustics
Materials Science
Biosensing Technology

Background:

Shear-horizontal surface acoustic wave (SHSAW) devices are promising for liquid-phase and biosensing due to their sensitivity to interfacial changes.
Weak guiding of SHSAW and strong generation of shear-horizontal bulk acoustic waves (SHBAWs) by interdigital transducers (IDTs) limit device efficiency.
Existing models for analyzing guiding structures in SHSAW devices have limitations regarding boundary conditions and electrode configurations.

Purpose of the Study:

To develop and validate a new computational model for analyzing uniform finite-thickness electrode guiding structures in SHSAW devices.
To improve the efficiency of SHSAW transduction (ηSHSAW) by optimizing guiding electrode design.
To enable accurate simulation of SHSAW devices for liquid-phase and biosensing applications.

Main Methods:

Utilized a hybrid finite and boundary element method (FEM/BEM) approach.
Integrated a finite-length uniform electrode structure with a quarter-wavelength electrode to model guiding effects.
Accounted for the finite thickness of all electrodes in the analysis.

Main Results:

Demonstrated that adjusting the quarter-wavelength electrode's properties can cancel SHSAW reflection, allowing the guiding electrode to be treated as infinitely long.
Achieved accurate prediction of SHSAW excitation directivity (9 dB) using the developed model.
Model simulations showed excellent agreement with experimental results from a fabricated SHSAW device.

Conclusions:

The developed model effectively analyzes uniform finite-thickness electrode guiding in SHSAW devices.
The improved understanding of guiding structures enhances SHSAW device efficiency for biosensing.
This work provides a validated tool for the design and optimization of advanced acoustic biosensors.
