Self-lubricating biomimetic systems

Definition

Self-lubricating biomimetic systems are innovative materials or designs inspired by nature that reduce friction and wear without the need for additional lubricants. These systems mimic natural mechanisms, such as those found in animal skins or plant surfaces, to achieve long-lasting lubrication through their inherent properties. This approach not only enhances performance but also promotes sustainability by minimizing the reliance on conventional lubricants.
