“…Surface acoustic wave (SAW) devices have numerous applications in the fields of actuators and sensors, including the microelectromechanical systems (MEMS) actuator [1]. SAW sensors have been applied in various fields, such as mechanical, biological, chemical, gas, and microfluidics, to measure physical quantities including temperature, pressure, viscosity, mass, stress, current, gas composition, magnetic field, and the spatial localization of partial discharges [2]- [9]. Recently, the wireless magnetic sensors with low energy consumption are essential for developments in the field of the internet of things, autonomous vehicles and the factory of the future.…”
