“…Based on the structural parameters of the PSC, the PSC sample was fabricated through the three-step method (cut-bonding circuit fill) described in Section . Compared with the commonly used cut-fill method and dice-insert method, the three-step method has the following characteristics: (1) front and back cutting ensures that the PZT-5A columns are evenly distributed to improve the uniformity of acoustic radiation; (2) no high temperature is involved in the preparation process, which avoids the depolarization of PZT-5A; , (3) the integrated cutting of PZT-5A is not limited by the area of composites. In conclusion, the novel PSC preparation method is reliable, efficient, and low cost without designing an auxiliary equipment such as pressing molds or polymer skeletons.…”

1-3 Piezoelectric composites have been widely used in underwater acoustic transducers because of their advanced electromechanical coupling properties relative to bulk piezoelectric ceramics. However, the existing applied composites are mainly rigid 1-3 PZT–epoxy resin composites, which have rigid structures and cannot be adapted to various sonar carriers with complex surfaces. Here, we design and develop a flexible 1-3 PZT–silicone rubber composite (PSC) for the first time. PSC combines a soft silicone rubber polymer in PZT with flexible embedded island-bridge conductive interconnects to enable the flexibility of both the piezoelectric sensing core and the electrical layer. The flexible wide bridge structure embedded in the polymer can cope with the large bending deformation of PSC with good conductive property, while the rigid thin island structure ensures the high acoustic performance of piezoelectric materials. A PSC sample is prepared with its structural parameters optimized via finite element analysis and is experimentally verified to have good flexibility, high electromechanical coupling coefficient (k t = 0.7), great thermal stability (from 25 to 105 °C), and bending stability (bending angle up to 215°). In addition, a preparation method for flexible 1-3 PSC is introduced, which has the advantages of high efficiency, low cost, no sample size restriction, and no high-temperature operation. The flexible 1-3 PSC in this work paves an important way for the development and application of the next generation of flexible underwater acoustic transducers.

“…To date, several studies have investigated the development of various, chemical, and thermally stable energy storage devices [54][55][56][57]. The bulk of such devices could be manufactured using various fabrication methods such as dice-and-fill [58], 3D printing [55], and 4D printing [59] and at a reduced cost. However, this can only be feasible and sustainable when the factors determining performance are highly modulated to reflect targeted function(s).…”

“…The experimental results show that the modified 1-3 type three-phase piezoelectric composites have higher electromechanical coupling coefficient and working bandwidth, lower characteristic impedance, and better decoupling effect than the traditional two-phase 1-3 piezoelectric composites. These modified composites have a great application prospect in nondestructive testing and medical ultrasound [ 47 , 48 ].…”

With the increasing demand for energy exchangers in underwater acoustic equipment, a modified 1-3 piezoelectric composite material is fabricated based on three-component phases. The new material outperforms the traditional two-phase 1-3 structure. Flexible silicone rubber polymer strengthened the piezoelectric composite and the properties of modified 1-3 piezoelectric composite have been tested by method of finite element simulation and experiment, respectively. This modified material has a high electromechanical coupling coefficient; the maximum can reach 0.684 and −3 dB bandwidth is superior to the two-phase 1-3 type. At the same time, the modified phase 1-3 type structure has an excellent decoupling effect. Silicone rubber can reduce the negative coupling vibration of epoxy resin, the vibration model simplification of piezoelectric composite, and the result of the experiment and simulation has good consistency.
