Acoustic power output measurements for thick-film PZT transducers
Electronics Letters, 40, (10), .
Direct acoustic measurements have been performed on a range of thick- film PZT ultrasonic transducer constructions, and these are compared with their electrical impedance and calculated input powers. They show good efficiency when driving into water, and a significant improvement over a similarly constructed bulk PZT transducer.
