New hydrophone technologyThe underwater acoustic transducer for receiving underwater acoustic signals is called a water hammer, and the hydrophone includes a piezoelectric type, a magnetostrictive type, a moving coil type, and a piezoresistive type. Here, w

Transducer characteristics and calibration methodsA hydroacoustic transducer is a device that converts acoustic energy and electrical energy each other. The position in sonar is similar to the antenna in a radio, an acoustic system that emits and receives sound waves in seawater. A piezoelectric tra

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

Many applications of piezoelectric ceramics in the precise instruments, including testing equipment, shock absorbing equipment and feeding equipment. In the application of these three aspects, various scholars have proposed different application methods. There are similarities and differences, and t

In the past 20 years,piezoelectric crystal cost has developed rapidly at home and abroad. Due to their advantages of simple production, low cost and good stability, they have been widely used in the fields of electronics, light, heat and acoustics, and have a wide range. Ultrasonic transducers are m

The increasingly performance of piezoelectric ceramic materials has made it the most widely used class of functional piezo ceramics. Not only used in industrial and civil products, such as ceramic filters, ceramic discriminators, ceramic attenuators in the communication equipment; underwater acousti

Since the curie brothers discovered the piezoelectric effect of tourmaline in 1880, piezoelectric science has officially entered the stage of human science and technology civilization. Early theoretical research was mainly done by the curie brothers later. In 1881, the curie brothers verified the in
