1.Development of ultrasonic piezoelectric transducer materials: (1) Piezoelectric composite transducers: At present, piezoelectric ceramics are the most commonly used materials in ultrasonic imaging transducers, with electromechanical conversion efficiency, easy to match with circuits, and undetermi

The bandwidth characteristic is an important indicator of the transducer. The bandwidth characteristics of the piezoelectric tubes transducer affects the spectral characteristics and waveform of the transmitted signal.Miscellaneous forms of signals and the use of modern signal processing techniques

A ultrasonic transducer is a device that converts mechanical vibration into electrical signals or mechanical vibrations driven by an electric field. Piezoelectric polymer electroacoustic devices utilize the transverse piezoelectric effect of the polymer, while transducer design utilizes polymer piez
