“…An array (1 × 5) hydrophone was introduced to evaluate the performance of a cymbal transducer known as a transducer capable of transmitting and receiving [ 87 ]. Between the piezoelectric materials PZT and PNS-PZT, the PNS-PZT material is recommended as a suitable material for hydrophones [ 88 ]. In addition, a 1 × 3 receiving array was configured linearly, and the effect of the coating material on the transducer was analyzed [ 89 ].…”

Interest in underwater transducers has persisted since the mid-1900s. Underwater transducers are designed in various shapes using various materials depending on the purpose of use, such as to achieve high power, improve broadband, and enhance beam steering. Therefore, in this study, an analysis is conducted according to the structural shape of the transducer, exterior material, and active material. By classifying transducers by structure, the transducer design trends and possible design issues can be identified. Researchers have constantly attempted new methods to improve the performance of transducers. In addition, a methodology to overcome this problem is presented. Finally, this review covers old and new research, and will serve as a reference for designers of underwater transducer.

Synthesis by mechanochemical activation route and optimisation for power harvesting properties of nano-structured Pb0.98La0.02(NiSb)0.05[(Zr0.52Ti0.48)0.995]0.95O3 [La-PNS-PZT] ferroelectric ceramic composition has been carried out and reported here for the first time. Progressive perovskite phase formation during mechanical activation from 5 h to 40 h followed by reactive sintering was analyzed from X-Ray Diffraction analysis. Noticeable formation of perovskite phase after10 h of milling and further its completion in successive reactive sintering was observed. Particle morphology of the 10 h activated nano-La-PNS-PZT powder analysed by High Resolution Transmission Electron Microscope (HRTEM) indicated average particle size (d50) of about 24nm. Microstructural studies of samples reactively sintered at 1220 °C were performed by Field Emission Scanning Electron Microscopy (FESEM) for powders activated for various durations, indicated the compact microstructure for 10 h activation which resulted in optimum piezoelectric properties viz. piezoelectric charge coefficient (d33=449x10-12 C/N), piezoelectric voltage coefficient (g33= 32x10-3 m-V/N), Figure of merit for power harvesting (14.4 x10-12 V-m-C/N2) accompanied by excellent stability of permittivity in the range -50 °C to 100 °C. The output voltage obtained from simulated random vibrations of aerospace vehicles at various Power Spectrum Density (PSD) values, measures about 3.0 mV output across resistance of 1 kΩ indicating suitability of composition for harvesting the power from aerospace vehicle vibrations.

“…Evaluating the performance of cymbal hydrophones, Li et al explored planar series and parallel arrangements of cymbal transducers for hydrophone applications [7]. In separate works, Li et al [8] utilized PMN-0.33PT, and Lonkar et al [9] employed PNS-PZT piezoelectric single crystals to propose cymbal hydrophones. They fabricated prototype hydrophones and compared their performance against that of a cymbal transducer made of PZT.…”

So far, cymbal transducers have been developed primarily for transmitting purposes, and even when used for receiving, the focus has been mostly on improving the receiving sensitivity. In this study, we developed a cymbal hydrophone with a higher sensitivity and a wider bandwidth than other existing hydrophones. First, the initial structure of the cymbal hydrophone was established, and then the effects of structural variables on the hydrophone’s performance were analyzed using the finite element method. Based on the analysis results, the structure having the highest sensitivity and widest bandwidth, with a receiving voltage sensitivity level above a certain threshold, was derived using optimal design techniques. A prototype of the cymbal hydrophone with the designed structure was fabricated, and its performance was measured, validating the effectiveness of the design by comparing the measurement results with the design values. The developed cymbal hydrophone is expected to be utilized in various underwater precision measurements, as it possesses a significantly broader reception frequency bandwidth when compared with other hydrophones used for the same purpose.
