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

Piezoelectric ceramic round tube is a commonly used for the acoustic transducer unit. It has simple structure, stable performance, convenient layout, uniform directivity along the radial direction and high sensitivity. Therefore, it is mostly used in the fields of underwater acoustics, geology and p

Combined with piezoelectric plane strain and three-dimensional piezoelasticity theory, the vibration characteristics of a piezoelectric ceramic thick hollow cylinder with radial polarization has been studied, and closed-type solutions are obtained for the mechanical radial displacement and electric

Biological fieldBiological piezoelectric ceramics are combined with lead free piezoelectric ceramics to form bio-piezoelectric ceramics. Nano-generators use zinc oxide to convert mechanical energy generated by human movement, muscle contraction, and body fluid flow into electrical energy, and supply
