Abstract: Electrical impedance matching network (EIMN) is important for the piezoelectric transducer to transmit high-power acoustic signal over a wide bandwidth. Different from the impedance matching ...
Abstract: This study presents a high fill-factor array of aluminum nitride (AlN) piezoelectric micromachined ultrasonic transducers (PMUTs) fabricated on a transparent substrate. PMUTs with diameters ...
