Popis: This paper presents, for the first time, an instrumentation technique for passively extracting a resonance frequency of a high-Q resonator across a wireless ultrasonic channel. As a first application, passive wireless measurement of temperature is presented along with a proof of concept of the wireless and passive operation of the device. Temperature resolution of 0.17 °C and a measurement range of 350 mm has been demonstrated.
