“…With the ever increasing pressures to reduce machine friction and wear, a number of investigators have turned to bio-inspiration to improve tribological performance. [1][2][3] One of these promising areas is the application of the lubrication mechanisms present in mammalian joints. In recent years, bio-inspiration has found importance in many fields of science and engineering.…”

A new lubrication model of poroelastic lubrication of materials with low Young’s modulus and permeability is presented based on Darcy’s law and linear elastic solid mechanics and a contact model. A rotating bearing surface moving against a flat surface is considered and the effect of material parameters and operating conditions is analyzed. The results show that the material parameters (permeability ( k), Young’s modulus ( E), and viscosity ( μ)) and operating conditions (angular velocity ( ω) and material deformation ( δ)) have significant effects on the lubrication performance of the poroelastic bio-inspired materials. It is also observed that the load ratio (the ratio of pressure-borne load to the applied load along the contact boundary) increases as k and E decrease, and as μ, ω, and δ increase. Conversely maximum solid stress decreases with decreasing of E, μ, ω, δ and with increasing of k. The relationship of the load ratio, contact stress, and deformation relative to E and k has been illustrated in this paper.

“…Many naturally occurring examples can be artificially replicated. The main ones concerning tribology in the human body are the skin sebum and the synovial fluid in joints, which provides low friction to cartilage [12,96]. Indeed, biomedical engineering is one of the main applications of biomimetic lubricants (for example, for arthrosis and osteoporosis treatments); the same mechanisms can be extended to other fields, e.g., cartilage lubrication-inspired seal lips in the automotive sector [97].…”

Sustainability has become of paramount importance, as evidenced by the increasing number of norms and regulations concerning various sectors. Due to its intrinsic trans-sectorial nature, tribology has drawn the attention of the supporters of sustainability. This discipline allows the environmental, economic, and social impacts to be decreased in a wide range of applications following the same strategies. In 2010, Nosonovsky and Bhushan drew up 12 approaches based on the 12 principles of green chemistry and the 12 principles of green engineering, defining the “12 principles of green tribology.” This review exploits the 12 principles of green tribology to fathom the developed research related to sustainability and tribology. Different approaches and innovative studies have been proposed in this short selection as references to consider for further development, pursuing the efforts of the scientific community for a sustainable future through the contribution also of tribosystems. The manuscript aims to provide practical examples of materials, lubricants, strategies, and technologies that have contributed to the overall progress of tribology, decreasing wear and friction and increasing efficiency, and at the same time promoting sustainable development, lowering toxicity, waste production, and loss of energy and resources.

“…While this issue requires the lubricants to be changed frequently, the absence of recyclability of the automobile lubricants causes environmental issues. Therefore, for these reasons, the researchers are now motivated to look toward nature for biomimetic lubricants [73] that are recyclable and eco-friendly. As per the current research trend, biomimetic lubricants can be considered as the future of tribology.…”

Automobile engineering often demands creative and innovative concepts to achieve their performance and efficiency targets. However, the strategies used to create these concepts are evolving with time. Recently, heightened attention has been noticed to using biomimetic concepts in the field of automobile design. The studies that apply biomimicry to automobile design often exhibit improvements in vehicle performance and fuel efficiency. Consequently, biomimetic concepts have extended an opportunity to the automobile industry to generate futuristic designs with advanced technology. However, the innovations and inventions in biology are usually published with more complex terminology that is not convenient for the research community working on automobile engineering. Hence, a notable delay is present in transferring the recent discoveries in biology to engineering researches so that they can develop strategies to mimic them. The purpose of this paper is to provide a brief overview of the biomimetic design approaches that have been and can be used in automobile design. In addition, the paper includes a classification of biomimetic concepts, which reveals the current research interests and highlights the areas with a deficit of research that is required to be addressed extensively in the future.
