“…By using a multimaterial 3D printer, composite materials of the stiff plate (VeroWhite) and soft matrix (TangoPlus) prototype were fabricated with different inclination angles and volume fractions (between stiff phase and soft material) [22]. In another study, 3D printing of the scales and substrate was done separately and they were assembled using glue [124].…”

Fish scales inspired materials platform can provide advanced mechanical properties and functionalities. These materials, inspired from fish scales take the form of either composite materials or multi-material discrete exoskeleton type structures. Over the last decade, they have been under intense scrutiny for generating tailorable and tunable stiffness, penetration and fracture resistance, buckling prevention, nonlinear damping, hydrodynamic and camouflaging functions. Such programmable behavior emerges from leveraging their unique morphology and structure-property relationships. Several advanced tools of characterization, manufacturing, modeling and computation have been employed to understand and discover their behavior. With the rapid proliferation of additive manufacturing (AM) techniques, and advancing envelope of modeling and computational methods, this field is seeing renewed efforts to realize even more ambitious designs. We present a review and recapitulation of the state-of-the art in fish scale inspired materials in this paper.

“…It is worth emphasizing that the scales on the body of the arapaima are arranged in an imbricate pattern [25][26][27][28]. Hence, the interaction effects of slippage, locking, and support between arapaima scales is a crucial factor influencing the animal's protection during attack.…”

The remarkable mechanical adaptability of arapaima (Arapaima gigas) scales has made them an important subject of study. However, no research has been conducted into their tribological properties, which are crucial for the protectability and flexibility of arapaimas. In this study, by combining morphological characterizations, friction experiments, and theoretical analyses, the relationship between the surface morphology and tribological properties of arapaima scales is determined. These results indicate that arapaima scales exhibit varying surface morphologies in different regions. More specifically, the exposed regions of scales feature grooves and a circulus, whereas the covered regions exhibit bumps. The specific surface morphology of arapaima scales produces varying tribological properties across different regions and sliding directions. The unique tribological properties of arapaima scales influence the forces received from predator attacks and neighboring scales, directly influencing the arapaima’s protective capabilities. This study provides new insights into the mechanisms of natural flexible dermal armors, and it has potential applications in personal protective systems.

As marine resources continue to be exploited, the remarkable locomotion and coordination of fish provide an excellent source of inspiration for scientists and engineers to design and control the next -generation autonomous underwater vehicles within a bionic framework. Underwater biomimetic robots combine bionics and robot technology, and their biological characteristics offer a lot of convenience for the robot so that it can obtain better performance in adaptability and robustness. Recently, with the combination of bionics, mechanics, electronics, materials science, and automation, there has been great progress in developing underwater bionic robots with different structure types and energy supply modes. This paper summarizes the research status of underwater robots, focuses on the research status of underwater bionic robots with different materials, types and motion modes, and introduces the propulsion mechanism of underwater robots with different structures and the control methods adopted in the propulsion process. Finally, the broad application prospect and market potential of underwater biomimetic robot are introduced.
