摘要：

The application fields of ultrasonic measurement systems are mainly determined by the properties of ultrasonic transducers. Acoustic features of transducers using piezoelectric polymer foils are considered. The directivity pattern and frequency range can easily be changed by variation of the geometric size and shape of such transducers. Their bandwidth is large in comparison to conventional piezoceramic transducers. Foil transducers offer new applications for ultrasonic sensors in connection with digital signal processing algorithms.
