Abstract: An ultrasonic transducer and a method for a transmitting an acoustic wave using an ultrasonic transducer comprising a membrane; two or more patterned top electrodes; a pMUT array, wherein the patterned top electrode is arranged as row pin selector and column selector in an N×N array; the pMUT array having N+N electrical contacts; a single unpatterned bottom electrode; a row and column where the electrode is at equal or opposite polarities; and a AC driving voltage is applied to top electrodes with a phase difference of zero or is applied to one electrode to transmit the ultrasonic wave.
