| Abstract: | The paper presents the results of experimental studies of radiating piezoelectric elements made on the basis of self-supported piezoelectric polymer films. The dependences of the sensitivity of these elements on the geometric parameters and frequency are investigated within a frequency band of 10?C70 kHz. A radiating device containing an ensemble of more than 4000 piezoelectric elements is constructed. |
