Abstract
We found experimentally that short monopole ultrasonic pulses can be radiat ed from a piezoelectric polymer film transducer driven by a step-function v oltage with a fast rising time and low output impedance. We clarified that the pulse width of the received ultrasonic monopole pulse depends on the ri sing time of step-function driving voltage, and is limited by transmission time (T-h) in the thickness direction of the film.
