Special Issue Information

Dear Colleagues,

The fascinating world of underwater life has long inspired technological innovation. In this Special Issue, titled "Research in Biomimetic Underwater Devices," we delve into the realm where biology and technology converge beneath the waves. Biomimicry in underwater environments involves understanding and emulating the adaptations of marine organisms to develop advanced technologies for various applications, ranging from underwater exploration and surveillance to environmental monitoring and marine resource management.

Aquatic creatures exhibit a wide array of unique abilities, such as efficient locomotion, pressure resistance, and energy conservation, which are of immense interest in engineering and robotics. By studying these organisms, scientists and engineers can design underwater devices that not only mimic their functionalities but also their resilience and efficiency.

In this Issue, we welcome original research, reviews, and insightful studies focusing on the development of underwater devices inspired by marine biology. Topics of interest include, but are not limited to, underwater robotics inspired by marine creatures, bio-inspired sensors and navigation systems, energy-efficient propulsion systems mimicking aquatic animals, and biomimetic materials for underwater use.

Through this interdisciplinary approach, we aim to foster advancements in underwater technology while deepening our understanding of marine biology. We encourage submissions from scientists and engineers in biology, robotics, mechanics, material science, and related fields who are working at the forefront of biomimetic underwater technology.

Hydrodynamic pressure sensors offer an auxiliary approach for ocean exploration by unmanned underwater vehicles (UUVs). However, existing hydrodynamic pressure sensors often lack the ability to monitor subtle hydrodynamic stimuli in deep-sea environments. In this study, we present the development of a deep-sea hydrodynamic pressure sensor (DSHPS) capable of operating over a wide range of water depths while maintaining exceptional hydrodynamic sensing performance. The DSHPS device was systematically optimized by considering factors such as piezoelectric polyvinylidene fluoride–trifluoroethylene/barium titanate [P(VDF-TrFE)/BTO] nanofibers, electrode configurations, sensing element dimensions, integrated circuits, and packaging strategies. The optimized DSHPS exhibited a remarkable pressure gradient response, achieving a minimum pressure difference detection capability of approximately 0.11 Pa. Additionally, the DSHPS demonstrated outstanding performance in the spatial positioning of dipole sources, which was elucidated through theoretical charge modeling and fluid–structure interaction (FSI) simulations. Furthermore, the integration of a high Young’s modulus packaging strategy inspired by fish skull morphology ensured reliable sensing capabilities of the DSHPS even at depths of 1000 m in the deep sea. The DSHPS also exhibited consistent and reproducible positioning performance for subtle hydrodynamic stimulus sources across this wide range of water depths. We envision that the development of the DSHPS not only enhances our understanding of the evolutionary aspects of deep-sea canal lateral lines but also paves the way for the advancement of artificial hydrodynamic pressure sensors.

Biological fish exhibit a remarkably broad-spectrum visual perception capability. Inspired by the eye arrangement of biological fish, we design a fish-like binocular vision system, thereby endowing underwater bionic robots with an exceptionally broad visual perception capacity. Firstly, based on the design principles of binocular visual field overlap and tangency to streamlined shapes, a fish-like vision system is developed for underwater robots, enabling wide-field underwater perception without a waterproof cover. Secondly, addressing the significant distortion and parallax of the vision system, a visual field stitching algorithm is proposed to merge the binocular fields of view and obtain a complete perception image. Thirdly, an orientation alignment method is proposed that draws scales for yaw and pitch angles in the stitched images to provide a reference for the orientation of objects of interest within the field of view. Finally, underwater experiments evaluate the perception capabilities of the fish-like vision system, confirming the effectiveness of the visual field stitching algorithm and the orientation alignment method. The results show that the constructed vision system, when used underwater, achieves a horizontal field of view of 306.56°. The conducted work advances the visual perception capabilities of underwater robots and presents a novel approach to and insight for fish-inspired visual systems. Full article
