In this review, we summarize cutting-edge research progress of biomimetic Bouligand architectures. Firstly, the natural Bouligand structures in animals, plants, and humans are introduced. On this basis, the relationship between properties and Bouligand structure is briefly discussed, including toughening mechanism, optical characteristics, and biological properties.
