Self-repairing behavior

Definition

Self-repairing behavior refers to the ability of materials to autonomously detect and heal damages or defects without external intervention. This characteristic is inspired by biological systems, where living organisms can mend injuries, ensuring structural integrity and functionality. By incorporating self-repair mechanisms, materials can enhance their lifespan, reduce maintenance costs, and improve performance in various applications, especially in demanding environments.
