Abstract

Surface acoustic wave (SAW) devices consisting of interdigitated transducers printed on piezoelectric substrates have resulted in low-cost, low-power, and small-footprint thermometers for high temperature and radioactive environments. This study developed temperature-dependent finite element models in both time- and frequencydomain. Modeling accuracy was evaluated using an aerosol-jet printed SAW thermometer measured from room temperature to 200 Celsius. Time-domain simulation results enabled acoustic wave propagation visualization and successfully guided the signal denoising of measured scattering parameters. Frequency-domain simulation accurately predicted the temperature-driven natural frequency drift in SAW transducers while maintaining high computational efficiency. The models developed in this study will facilitate computer-aided design of future SAW transducers and expand their applications in harsh environments.
