Definition: A structural organization in which a material is arranged across multiple length scales (e.g., atomic, nano, micro, macro), with each level contributing distinct structural or functional properties. These hierarchies often lead to enhanced or synergistic performance characteristics.
Example: Bone exhibits a hierarchical structure: from collagen molecules (nanometer scale), to mineralized fibrils (microscale), to trabecular and cortical architectures (macroscale), each level contributes to its strength and toughness.
