What We Can Learn From

Animals?

each animals has its own uniquecapabilities

some animals have hydrodynamic

form (movement in water)

others use outlandish sensorydevices

Inspired scientist to invent new

devices that can make work/human life

Surface Drag and SwimsuitsInspired by Shark Skin

- These tight fitting suits aremade out of a fabric which wasdesigned to mimic the properties ofa shark's skin by superimposingvertical resin stripes.

- Swimsuits made with new fibers

and weaving techniques are producedto cling tightly to the swimmer'sbody and reduce drag as much aspossible. Research has shown thatsuch garments can reduce drag by 8%over ordinary swimsuits

515-Million-Year-Old Optic Design

- Andrew R. Parker and his colleagues

- how to greatly increase the efficiency ofsolar absorbers and solar panels used to provide

energy for satellites.

- Work is currently under way to reduce the

angular reflection of infrared (heat) and other light

waves by mimicking the fly-eye structure.

- Most suitable for use in solar panel surfaces,the fly-eye grating has also done away with the

necessity for expensive equipment to ensure that these

panels are always directly facing the Sun.

A Solution to Traffic Problems

from Locusts!

Locusts never collide with one another led to theopening of a whole new scientific horizon

Experiments determined that locusts send out an

electronic signal to any body approaching them to

identify that body's location, and then change

direction

This behavior of locusts is being studied that mightbe the solution for heavy traffics

Stenocara: A Fully-Fledged WaterCapturing Unit

- the stenocara's water capture system is

basically a special feature in its back where thesurface is covered in tiny bumps.

- the surface of the regions between each bumpis wax-coated tpyet the bumps themselves are waxfree which lets them collect water productively.

-they extract water vapor from the air which israre because the desert evaporates the droplets

almost immediately due to heat and wind. But dueto its unique design the droplets form on thewings of the stenocara and and the droplets slideto the beetles mouth

- after further examination on the beetlescientist have establishednthabit is a perfectwater trapping model

Birds Flight Methods as a Model for

High-Speed Trains

Bullet Train Has a Nose

Like a Kingfisher Beak The kingfisher dives into the water from

the air without making a splash, mostlythanks to its highly efficiently-shapedbeak.

Eiji Nakatsu realized that the sameshape could solve Japans ultra-fastbullet trains, which created a loudbooming sound like a thunder clap wheneverthey exited a tunnel.

The nose of the train was pushing air athigh speeds, creating a wall of wind thatnot only made the loud sound, but alsoslowed down the train.

The new, kingfisher-inspired train noseeliminates this problem, making the trainsup to 20 percent more fuel efficient.

Owl Flight and High-Speed Train Noise

-owls make the least noise during flight(this is because they're wings have smalltoothed feathers called serrations)

-since owl's have serrations they formsmaller vortexes compared to other birds

thus being minimizing noise during flight

- the Japanese tested on stuffed owlstherefore witnessing the perfect wing designof the said bird

- now they succeeded in reducing the noiseof they're trains using wing shapedpantographs based on the owl's serration

Peacock Feathers and Self-Changing Display Signs

- Keratin protein together with the

brown feather pigment melenin allowlight to refract so we can see thecolors.

- The Japanese were inspired to developreusable display signs, thuseliminating some colors as to display

the desired message ,- -The signs can be used repeatedly andimprint new images

- -With this technology we eliminate theidea of producing new signs as well aswe prevent the use of toxic paints

Bird Skulls Inspire

Lighter, Stronger

Building Materials

Skulls in general are extraordinary

impact-resistant structures and extremely

light at the same time as they protect

the most important organs of an animal

body and this performance and physical

property can be applied in structure or

architecture design, says architect

Andres Harris,

Harris imagines mimicking the materialfor a large pavilion, and the blog

Biomimetic Architecture notes that this

concept could also be applied to cars.

Bio-Inspired Computer

Takes Cues from Cat Brains

The University of Michigan decided to study

the feline brain in order to develop an

intelligent computer.

The idea is that current computers execute

code in a linear fashion, as opposed to the

mammalian brain, which can process many

things at once.

Lu is in the process of developing a

circuit element that behaves like biological

synapses. This memristor can remember past

voltages that passed through it in a way

that is similar to memory and learning in

the brain. Why cats? Computer engineer Wei

Lu says it was simply a more realistic goal

than mimicking the brain of a human.

Bat Sonar Navigation Helps theBlind Get Around

Ultracane wouldnt be possible without study of the waybats get around in pitch blackness.

In the same way that bats can see in the dark using

ultrasonic echoes that reveal the location of obstacles,the Ultracane warns blind users of objects in their path.

A number of sensors on the cane even make it possible forusers to sense objects higher than head height.

Deer Antlers Inspire

Basis of Super-Tough

Materials

Scientists at the University of York in

the UK studied antlers that were cut just

before the stage when stags start dueling,

when they need their antlers to be at

their strongest, and discovered that

during this period, the antlers dry out.

Dry, stiff materials are usually brittle

and easily breakable, but deer antlers

proved to be 2.4 times stronger than wetbone.

engineers: making a material that is both

stiff and tough. The structure of deer

antlers will likely become the basis of

such.

Contact Lenses ofthe Future Inspiredby Gecko Eyes

Scientists have discovered thatgeckos have a series of distinct

concentric zones in their eyes thatmake it possible for them to seecolors at night, an ability fewother creatures have.

These zones have differentrefractive powers, giving geckos amultifocal optical system thatallows light of differentwavelengths to focus on the retinaat the same time.

This makes their eyes 350 timesmore sensitive than humans, andlets them focus on objects atdifferent distances.

The discovery may allow engineersto develop more effective camerasand possibly even multi-focalcontact lenses.

Beer-Foam-Like Bird Feather

Colors Influence Optical

Materials

that shade of blue is

actually produced bynanostructures that self-assemble

in much the same way as beer foam.

color-producing structures in

feathers start out as bubbles of

water inside living cells, and are

replaced with air as the feathergrows. These intricate optical

structures, which look like

sponges with air bubbles under a

microscope, are being used to

create a new generation of optical

materials in the lab.
