Презентация "Biomimicry"

Copying someone else's work or invention without attribution is called plagiarism. But, despite the fact that plagiarism is usually considered something wrong, oddly enough, it led to the emergence of a completely new scientific field - biomimicry. As the name suggests, biomimicry is an imitation or copying of technological ideas found in the biological world.

Слайд 3

Let's start with the simplest example. This is Georges De Mestral, it was he who invented sticky fasteners on clothes. Mestral loved to hunt with dogs and noticed how dogs collect a lot of thorns.

Слайд 4

He saw one of these spines under the microscope and saw hooks with which they clung to wool.

Слайд 5

Then, Mestral decided to repeat this mechanism in clothes, only he made hooks from nylon so that it would serve longer.

Слайд 6

And this is the first level of biomimicry - copying forms . in this case, the engineer should look closely enough at the animal to see its potential.

Слайд 7

Next comes the second level - hidden properties . It means that we can create analogues of natural mechanisms that are not similar to the original, but with the same functionality.

Слайд 8

We look at the woodpecker. They knock 22 times a second and reach 12,000 a day. One hit of a woodpecker creates loads of 1200 G. While, with 5 G, people lose consciousness.

Слайд 9

But the woodpecker has 4 fixtures that protect it. It is tough, but at the same time elastic beak.

Слайд 10

Porous skull

Слайд 11

Small compartment with fluid that cushions the blows.

Слайд 12

And springy bone that supports the tongue.

Слайд 13

Engineers were able to reproduce all these mechanisms to protect fragile electronics.

Слайд 14

The protective capsule has a body made of steel.

Слайд 15

Aluminum soft layer

Слайд 16

Rubber support

Слайд 17

And a large number of glass beads

Слайд 18

Richard Hammond made such a capsule, put an ordinary light bulb there and threw it from space.

Слайд 19

The light bulb remained intact.

Слайд 20

Such protection is perfect for black boxes on airplanes.

Слайд 21

And also, to protect orbital stations from space rubbish .

Слайд 22

Perhaps scientists in different spheres of life, such as architecture, energy and chemistry, should not invent something new. You just need to look at the genius creator - nature.
