The PolySense team has just published a new article on Advanced Materials Technologies Journal (IF 6.2)
reporting on the development and experimental validation of a full-domain 3D digital twin for a SSAW device based on 128° YX LiNbO3 ,commonly used for acoustofluidic applications. The model is developed in COMSOL Multiphysics to accurately capture the electromechanical interactions that govern SSAW generation and its interaction with the substrate. Its predictive accuracy is validated through electrical characterization with a vectornetwork analyzer and surface displacement mapping with a laser Doppler vibrometer, demonstrating strong agreement between simulations and experimental data. This validation proves the reliability of digital twins for predictive modeling and design optimization of SSAW devices, offering a more precise and efficient alternative to traditional models and trial-and-error approaches.
