Plant structure bionics is based on the principles of engineering mechanics.
With inspiration from the forms and functions of plants at different levels (micro, meso and macro), the materials, structures and systems of plants are imitated to improve efficiency of engineering structures [2].
Structural bionics involves multi-disciplines, such as botany, plant physiology, soil science, optics, biophysics, biochemistry, physics, electronics, ergonomics, psychology, materials science, mechanics, dynamics, control theory, engineering, economics, color, aesthetics, communication, ethics and social science.
To improve integrated performance of intelligent building materials, and expand their engineering applications have become key steps to further develop intelligent building materials.
