“…These characteristics may be adapted for different functions. The cusp at both the outer enamel and sulcal enamel can penetrate the bamboo, and the ridge has a cutting function [21]. The fossae structure provides a channel for accommodating the bamboo and also increases the sharpness of the ridge.…”

Chinese bamboo rats consume a diet that consists mainly mechanically demanding bamboo. The ability of the rats to process food depends on the capacity of their teeth to resist wear during biting and chewing. The mechanisms of the bamboo rat teeth were determined by investigating and correlating the structure and tribological properties of the teeth. The rat's incisor has a cutting-edge cusp and outer enamel iron pigmentation, making the teeth harder, more resistant to acid attacks, and improving the resistance to cracking. Additionally, the incisor is designed to self-sharpen. The complex morphology at the macroscale, and the three-dimensional fabric body formed by densely packed rods and inter-rods at the microscale of molar enamel benefit molar rapid capture and effective breaking of bamboo, resisting the high stresses required to process bamboo without wear. The results of the structure-function relations of bamboo rat teeth in this study may provide new ideas for improving plant cutting and grinding tools.

“…Zhang et al developed a bionic imprinting toothed wheel inspired by the foreleg end-tooth of soil-burrowing dung beetle, eventually reducing the forward resistance and expanding the volume of imprinted microbasin [ 10 ]. To improve the crushing performance in powder processing, bionic grinding heads based on natural friction pairs of bovine teeth were presented by Wang et al, enabling a higher reduction ratio and lower working temperature effectively [ 11 , 12 ]. The above typical bionic structures have achieved good application effects in either cutting or grinding tools, whereas transferring geometric characteristics of natural teeth to crimping structures is rare.…”

“…Vollmerhaus et al once studied the various geometries of the infundibulum dentis during the life cycle of horses and inferred that this construction results in a good grip of the occlusal surface and the efficiency of ingestion [ 17 ]. Wang et al further showed its holding function in the chewing simulation of bovine molars and developed biomimetic high-performance grinding heads, which has been demonstrated experimentally [ 11 , 12 ]. Also, Weimer et al indicated the potential for biomimetic application of ruminant infundibulum dentis to holding design in a bioreactor [ 18 ].…”

It is highly desirable to improve the anti-slipping stability of the crimping structure for a reliable connection. This study innovatively presents a biomimetic strategy for designing a high-performance crimping structure for industrial hose assembly based on evidence that the special infundibulum dentis structure on the occlusal surface of ruminant molars has the potential of anti-slippage and can also reduce the risk of stress concentration. Utilizing reverse engineering technology, the three-dimensional (3D) digital model of the bovine molar was built as a representative prototype, and then corresponding characteristics of the infundibulum dentis were extracted with a fitting method for the bionic design of the crimping structure. Numerical simulations and experimental results both indicate that the bionic crimping structure has high resistance to slippage of hose body compared with the traditional type, and further, the formation mechanism of bionic anti-slipping performance was discussed.

“…Natural organisms live in harsh and complex environments for long periods, so their body surfaces must possess a strong ability to resist external damage. A non-smooth morphology, non-smooth structure, and different material compositions on the surface of the organism are typical biological coupling characteristics [1][2][3][4][5]. Various non-smooth features provide an organism with an appropriate combination of strength and toughness and play a unique role in resisting external alternating stress or direct damage.…”

To study the effect of laser biomimetic treatment on different material compositions, five kinds of steels with different carbon element contents were studied by laser remelting. The characteristics (depth, width), microstructure, hardness, tensile properties, and wear resistance of the samples were compared. The results show that when the laser processing parameters are fixed, the characteristics of the unit increase with an increase of carbon element content. Moreover, the hardness of the unit also increases. Compared with the untreated samples, when the carbon content is 0.15–0.45%, the tensile strength of the laser biomimetic samples is higher than that of the untreated samples. For the biomimetic samples with different carbon content, with an increase of carbon content, the tensile strength increases first and then decreases, while the plasticity of the biomimetic samples decreases continuously. The bionic samples have better wear resistance than that of the untreated samples. For bionic specimens with different carbon elements, wear resistance increases with an increase of carbon element content.
