Biological structure characteristics applicated in mechanical bionic design

Bionics is a growing field that has the potential to drive engineering advances. This research focuses on investigating the characteristics of biological structures with illustrations of successful mechanical bionic designs. After natural selection, they exhibit remarkable optimized capabilities and igneous structures from macro-meso-micro(nano) scales, which can be extracted for achieving maximal performance from minimal resources. The similarities and differences between biological and mechanical structures are summarized. The current state and application prospect is presented and discussed, indicating that the structural bionics is challenging but promising for updating traditional mechanical design concepts and achieving maximum structural efficiency.
