Enhanced Sensitivity of FeGa Thin-Film Coated SAW Current Sensor

Enhanced Sensitivity of FeGa Thin-Film Coated SAW Current Sensor

A surface acoustic wave (SAW) device is proposed for sensing current by employing the patterned FeGa thin film as the sensitive interface. The layered media structure of FeGa/SiO<sub>2</sub>/LiNbO<sub>3</sub> was established to reveal the working principle of the sensors, and...
