Modern technology is based on which animals are invented

Hehe

Radar was invented based on the fact that bats can fly at night without using their eyes, and the bat can detect any obstacle that blocks it with ultrasound waves emitted by its ears and mouth, so that the exact location of these obstacles is displayed in the bat's brain, and the bat will not hit any obstacles.

But on the contrary, if you plug the bat's ears and mouth, it will stumble like a headless fly. Radar is also the principle of bats emitting ultrasound waves, and they detect obstacles through ultrasound waves!

Extended Materials. Among mammals, dolphins and bats (yes, bats are mammals) are both experts at positioning.

Humans interfered with the sound of a pair of dolphins. She uses instruments to simulate dolphin sounds, trying to disrupt the dolphin's reception of its own sound waves. As a result, dolphins either change the frequency of their own sound waves or change the timing of their vocalizations. Both of these strategies allow dolphins to successfully filter out interfering sound waves.

And in the study of bats, Kloepper used a "biological drone" - a specially trained hawk. The eagle has a small video recorder and microphone strapped to its body. The eagle flies into the bat colony and records the sounds of the bats.

If you use a real drone to fly into a dense swarm of bats, the effect may not be as good as that of an eagle. Still, if the bat swarm is not dense, drones are still well used.

Two studies comparing each other found that bats spoke for 20 times longer than dolphins. Because of this, Kloepper argues, it's easier for bats to make subtle and layered adjustments. In the event of signal interference, bats are able to take a detailed solution.

Dolphin sound waves, like snapping your fingers; The bat, however, seems to whistle. Snap your fingers, it's pretty much the same every time. Whistling can be complicated and play a different tune.

The study also found that bats can not only track their prey, but also learn the texture of different prey. Bats aren't necessarily stronger than dolphins, but bats score higher in radar detection, Kloepper says.

Inventions inspired by animals in life are:The helmet was invented based on the woodpecker, the radar was invented according to the bent band according to the bat, the electronic frog eye was invented according to the frog eye, the bulletproof ** was invented according to the beetle, the volt battery was invented according to the electric fish, the compound eye digital camera was invented by the compound eye structure of bees and flies, the submarine was invented according to the shape of the whale, the airplane was invented according to the study of birds, etc.

Radar principle. Bats use the "ultra-hidden cracked sound wave" to navigate at night. The larynx of the bat emits a high-frequency sound wave that is more than the human ear can hear, and this sound wave travels in a straight line and returns quickly as soon as it touches an object, and the bat receives this returning ultrasound wave with its ear, so that it can make accurate judgments and guide the bat to fly.

Radar uses this characteristic to create radar based on the echolocation system of bats with the help of the principle of biomimicry.
