Abstract
An ultrasonic sensor array includes a plurality of ultrasonic transducers, each transducer including a piezoelectric member. Each of the transducers includes an electret member, a receive (Rx) layer configured to exhibit a first d33 resonating mode coefficient and a transmit (Tx) layer configured to exhibit a second d33 resonating mode coefficient, the first coefficient being different from the second coefficient. The transducers are disposed on a flexible substrate.
