Research Progress and Development Trends in Biotribology: Multi-Field Coupling at Biological Interfaces

A key focus is on biological interfaces such as joints, skin, and cardiovascular systems, where friction, wear, and lubrication critically impact device performance and tissue health. For instance, studies of artificial joints reveal how mechanical stress and biochemical processes interact, influencing wear patterns and material degradation. Research has identified that the integration of nanoscale structural modifications and bioinspired lubrication mechanisms, such as polymer brushes mimicking natural cartilage, significantly reduces friction coefficients and wear rates.

In the context of cartilage repair, the use of hydrogel-based materials with self-renewing lubrication layers has shown promise in restoring joint function and mitigating osteoarthritis progression. Meanwhile, advancements in implantable materials, including hydrophilic coatings and biocompatible polymers, have enhanced device performance in corrosive and dynamic biological environments. The study also highlights the critical role of interdisciplinary collaboration in addressing the challenges of optimizing artificial implants and developing biomimetic systems.

Future research directions include improving the understanding of multi-field coupling effects at biological interfaces, optimizing the structural and functional integration of biomaterials, and extending applications beyond traditional medical devices to areas such as drug delivery and tissue engineering. This work provides a foundation for advancing biotribology through the integration of multidisciplinary approaches, offering solutions for critical medical and engineering challenges in healthcare and beyond.
