Control bionics:

By imitating functions such as orientation, navigation, move control and feedback regulation of organisms, we can create new control systems.

Examples: In the field of computer science, the study of bionics has produced artificial neurons, artificial neural networks, and swarm intelligence.

Chemical bionics:

By imitating organisms' catalytic actions, synthesis, and energy transformation, we can create chemical products, and develop chemical technology and new energy.

A classical example is the development of dirt- and water-repellent paint (coating) from the observation that the surface of the lotus flower plant is practically unsticky for anything (the lotus effect). This as also been covered under Information bionics.

Thus, we can know that the methodology of bionic design is based on the idea of organisms characters.
