Abstract
A method includes receiving, by a piezoelectric stack of a transducer, a first piezoelectric voltage. The transducer has a base structure and a first layer, the base structure having a first displacement between a first portion of the base structure and the first layer. The method also includes transmitting, by the transducer, a first ultrasound frequency while receiving a first piezoelectric voltage, and receiving, by the transducer, a first bias voltage. The received first bias voltage alters the first displacement between the first portion of the base structure and the first layer, and the altered first displacement is smaller than the first displacement. The method further includes receiving, by the piezoelectric stack of the transducer, a second piezoelectric voltage to the transducer, and transmitting, by the transducer, a second ultrasound frequency while receiving the first bias voltage and the second piezoelectric voltage.
