Birds fly in the sky: they make all kinds of flying machines.

Bees build nests: various hexagonal honeycomb structural plates.

Every dragonfly has a slightly heavier point at the end of its wing than its surroundings, which is the key to prevent its wings from shaking. Aircraft designers study the flight methods of flies, mosquitoes, bees, etc. , and created many new aircraft with various excellent performances.

Whale: the shape is ideal "streamline", and "streamline" has the least resistance in water. Later, engineers imitated the shape of whales, improved the design of the hull and greatly increased the speed of the ship at the stern.

Eggshell: it can evenly distribute the pressure to all parts of the eggshell. According to the characteristics of this "thin shell structure", architects have designed many buildings that are both light and material-saving.

Kangaroo: A jumping cross-country car.

Shell: A tank with a solid shell ...

Fish swimming in the water: learned to swim and invented the submarine.

One-piece shark suit: The first generation shark suit imitates the shark's skin, and some rough dentate protrusions are designed on the swimsuit to effectively guide the water flow, tighten the body and avoid the vibration of the skin and muscles. The second generation of shark clothing has added some new highlights, adding a material called "elastic skin", which can reduce people's resistance in water by 4%. In addition, two accessories have been added, and the bumper made of titanium silicone attached to the forearm can make athletes swim more easily; Vibration control systems attached to the chest and shoulders can help guide the water flow.

Let the blind see the light: After implanting tiny bionic retina, three blind patients not only saw flashing or moving light spots, but even successfully distinguished cups and plates with their eyes.

Synthetic spider silk: Spider silk contains a fibrin similar to keratin in hair and horns. This protein began to become tough after it was secreted. By carefully balancing the moisture content, spiders and silkworms can prevent fibrin from curing too fast.

From fireflies to artificial luminescence. Because this lamp has no power supply and does not produce magnetic field, it can be used to clear magnetic mines under the irradiation of biological light source.

Electric fish and volt batteries. Through the anatomical study of the electric fish, it is found that there is a strange power generation organ in the electric fish. Italian physicist Volt designed the world's earliest voltaic battery based on electric fish power generation organs.

Jellyfish Ear: A storm predictor for jellyfish ears, which accurately simulates the organs that jellyfish feel infrasound.
