WebPiezoelectric micromachined ultrasonic transducer (pMUT) rangefinders have been rapidly developed in the last decade. With high output pressure to enable long-range detection and low power consumption (16 μW for over 1 m range detection has been reported), pMUT rangefinders have drawn extensive attention to mobile range-finding. pMUT rangefinders … Webarrays. No spurious mode was found in the 7x7 array. However, a small spurious mode starts to appear in the 9x9 array at around 6.5 MHz. The position of this spurious mode … WebIn this work, we reported a theoretical model for a novel piezoelectric micromachined ultrasonic transducer (PMUT).
