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

Submarine intelligent includes underwater acoustic communication,One of the technical difficulties to overcome the intelligent for submarine pipeline maintenance is how to realize the underwater communication system of the intelligent to complete the remote operation of the platform. Due to the par

Precise mechanical cutting method:Precision mechanical cutting is a common method of manufacturing piezoelectric micro devices. It uses a diamond cutter to cut a block of piezoelectric material or a thick film into micropillars and arrange them into an array for further assembly into a device. Howev
