Directional droplet transportation without extra energy input remains a challenge in microfluidic biochips for clinical detections. Herein, inspired by the water-collecting behaviors on cactus spine, we fabricate nanomaterial-based superwettable microspine (SMS) chips. The bioinspired SMS chips are capable of spontaneous and directional synergistically combining geometric asymmetry surface superhydrophilicity. Based theoretical models, gradient Laplace pressure arising from chip can dominate...
There are many factors that determine the performance parameters of piezoelectric ceramics, but process preparing ceramics plays a decisive role in their properties. By improving preparation process, significant improvements ceramic properties can be achieved. In order to meet growing demand for improvement various crystal methods such as Template Crystal Growth (TGG), Reflected (RTGG), and Oriented Curding (OCAP) techniques have been used ceramics. This article first introduces then...
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 are mainly rigid PZT–epoxy resin composites, which structures and cannot be adapted various sonar carriers with complex surfaces. Here, we design develop a flexible PZT–silicone rubber composite (PSC) for first time. PSC combines soft silicone polymer PZT embedded...
In recent years, hydroacoustic transducers made of PZT/epoxy composites have been extensively employed in underwater detection, communication, and recognition for their high energy conversion efficiency. Despite the ease with which these can be formed into complex shapes, lack mechanical flexibility limits versatility across various sizes vehicles. This study introduces a novel flexible piezoelectric composite transducer (FPCHT) based on 1-3 PZT-5A/silicone rubber an island–bridge electrode,...

Piezoelectric composites have been widely used in high-frequency transducers because of their good vibration characteristics, high-electro- mechanical conversion efficiency, and large bandwidth. However, compared with piezoelectric ceramics, the disadvantage high loss, this leads to much heat generation under excitation high-power electrical signals. As a result, composite often suffer from internal temperatures during operation, which turn affects acoustic performance. To address problem,...
The bending deformation of piezoelectric composite resonators under temperature variations can significantly impact transducers and sonar systems, yet there is a lack research on how to assess these deformations. Investigating testing methods for the at different temperatures not only provides reliable basis selecting suitable but also advances design fabrication processes relevant materials. This crucial enhancing performance systems. A study has designed system based fiber Bragg grating...
Polymeric hydrogel materials have excellent electrical conductivity and mechanical properties will be potentially used in wearable electronic devices, soft robotics, medical treatment.
