Biomimetics

Definition :the examination of nature, its models, systems, processes, and elements to emulate or take inspiration from the nature in order to solve Human problems.

History :biomimicry & biomimetics come from the Greek words bios (life) and mimesis(imitate). Other term often used are :bio-inspiration, bionics, and biognosis.

Examples of Nature’s Perfection Hummingbirds' ability to cross the Gulf of Mexico on less than 3 g of fuel How dragonflies are more maneuverable than even the best helicopters The heating & air conditioning systems in termite mounds—in terms of

equipment/energy consumption, far superior to those constructed by man Bats’ HF transmitter, far more efficient and sensitive than radar systems

created by human beings, How light-emitting algae combine different chemical substances to give

off light without heat How arctic fish and temperate-zone frogs return to life after being frozen,

with the ice doing their organs no harm How anole lizards and chameleons change their colors—and how octopi

and cuttlefish change both their colors and patterns in a moment—to blend in with their surroundings

Bees’, turtles’ and birds’ ability to navigate without maps Whales & penguins diving underwater for long periods w/o scuba gear How the DNA helix stores information in all living things, How, through photosynthesis, leaves perform an astounding chemical

reaction to create 300 billion tons of sugar every year.

Abalone ShellInner shell of Abalone is twice as resistant as the ceramicAbalone shell is composed of microscopic brick wall, with calciumcarbonate tiles stacked like ‘bricks’ alternating with clingy protein‘mortar’

- Lamination helps keep cracks from propagation. - When struck, the tiles slide instead of shattering and the proteinstretches to absorb the energy of the blow

Mother-of-Pearl

Nacre structure of the inner layers of a mollusk shell hasbeen imitated in the development of materials for use insuper-tough jet engine blades. 95% of the mother-of-pearl consists of chalk, due to itscomposite structure it is 3,000 times tougher than chalk. Microplatelets 8 μm across, 0.5 μm thick, arranged in layerPlatelets is dense and crystalline of calcium carbonatewith sticky silk-like protein.When stressed by heavy load, any cracks that form begin to spread, but change direction as they attempt to passthrough the protein layers. This prevents fractures. If a crack forms, the protein layers stretch out into strandsacross the fracture, absorbing the energy

Such structure reduces damage
