1. Based on the principle of the bat's ultrasonic locator, people also imitated the "pathfinder" for the blind. With an ultrasonic transmitter inside the device, a blind person can spot poles, steps, people on bridges, etc. Today, a similar function of the "pathfinder" has been developed. Nowadays, "ultrasonic glasses" with similar effects have also been made.

2Simulating the incomplete photosynthesizer of cyanobacteria, a device for bionic photolysis of water will be devised, which will make it possible to obtain large quantities of hydrogen.

5. An electronic frog eye has been developed based on the visual principle of the frog eye. This kind of electronic frog's eye can be like the real frog's eye, accurately recognize the specific shape of the object. After the electronic frog's eye is installed into the radar system, the radar anti-interference ability is greatly improved. This kind of radar system can quickly and accurately identify specific shapes of airplanes, ships and missiles. In particular, it is able to distinguish between real and fake missiles and prevent them from being mistaken for real.

Electronic frog eyes are also widely used in airports and transportation routes. In the airport, it can monitor the takeoff and landing of the aircraft, if found to be about to collide with the aircraft, it can issue a timely warning. In the traffic road, it can direct the movement of vehicles, to prevent vehicle collision accidents.

6. from fireflies to artificial cold light; 3. electric fish and volt batteries; 4. jellyfish's wind ear, modeled on the structure and function of jellyfish ears, designed the jellyfish ear storm predictor, can be 15 hours in advance to the storm forecast, the safety of navigation and fisheries are of great significance.

7. By the annoying fly, the imitation of a very strange small gas analyzer. Has been installed in the cockpit of the spaceship, used to detect the composition of the gas in the cabin.

8. Based on the study of the human bone and muscle system and bioelectric control, the manpower enhancer - walking machine has been imitated.

9. The hooks of modern cranes originated in the claws of many animals.

10. roof corrugations mimic the scaly armor of animals.

11. Boat oars mimic the fins of fish.

12. The saw imitates the arm of a praying mantis, or serrated grass.

13. The crocus plant took inspiration to invent Velcro.

14. The sniffing lobster provided the idea for making odor detectors.

15. Gecko toes offer encouraging prospects for making sticky audio tapes that can be used over and over again.

16. The shellfish uses its proteins to produce a colloid so strong that such a colloid could be used in everything from surgical sutures to mending ships.
