A new type of surface acoustic wave temperatureSensor device
A new type of surface acoustic wave temperatureSensor devicesensor The heat radiation loss caused by the high temperature environment will cause the sensor device to have a greater attenuation of sound waves, so the sensor working in this environment should have a sufficiently large quality factor and low loss.
Traditional wired active sensors cannot be used for temperature measurement in high temperature environments, and wireless passive temperature sensors based on surface acoustic waves provide a good solution for this.
