In this paper, we report a high-sensitivity hydrogen leakage sensor for new-energy vehicles based on our originally designed AT-cut quartz resonator. Firstly, as optimization work, we established a finite element model and carried out an eigenfrequency analysis to find the optimal dimensions of the sensor. Secondly, as verification work, the sensor was fabricated using our newly developed etching process and evaluated. The simulated frequency was basically in agreement with the measured frequency, and good energy-trapping performance and decoupling characteristics were realized, which confirm the validity of our optimal design. Finally, the sensitivity of the sensor was examined experimentally, and good sensitivity was achieved.
