“Bio-inspired systems”

Bionic Systems(popular definition)

� super-powers

generally associated to

Let us remind the definition of “Bionic Systems” we already know:

Bio-inspired systems______________________________________________________________________________________________________________________________________________________________________________________

bionic a. [f. bio- + electronic.]having electro-mechanical body parts, or superhuman powers resulting from these.

Also in trivial use: powerful, energetic.

Bionics?

Bionic Systems

popular definition

bionics n.

the study and the construction of systems that function like (parts of) living beings.

from fiction from scientific fiction


Bionic Systems(another interpretation)(scientific interpretation)

and now we will see


Bionic Systems

scientific version:

bionic = βίον + ic.

bionic: s. f. Biol.

The study of functions, characteristics and phenomena observed in the living beings, in order to apply such knowledge in the

conception of new techniques and in the creation of new devices

and machines.

The term bionics was coined by Jack E. Steele in 1958 while working at the Aeronautics Division House at Wright-Patterson Air

Force Base in Dayton, Ohio, USA.


Bionic Systems� biomimetic systems (Biomimetics)

or

� bioinspired systems

When science is inspired by nature

1) imitating their models, or

2) valorizing their knowledge, or

3) changing the paradigm of just extracting

a) by learning from nature, or

b) by doing the things in the way that nature does.


The benefits from the bio-inspired systems can be seen in several applications, including aerodynamics of vehicles, structures,multifunctional materials, drugs, robots, etc., etc.

Bio-inspired systems are becoming common in some scientific environments, and it is connected with the work of several scientists (engineers, chemists, physicians, biologists, etc.) that look for copying the biological processes and apply them in different areas of technology and science.

The fundamental idea is:

“If nature took millions of years to improve their own mechanisms, why not to copy them?”


they are twice harder than the ceramics produced by technology

threads of a spider web are five times more resistant than steel

marine shells

spiders

When talking about adapting the form to the function, naturegives us several examples:


It is a calcareous substance, hard and shining. It is produced mainly by bivalves mollusks

mother of pearl

inspiration for:the hardest ceramics once made by man

other applications such as the conception of prosthesis


even under the water, they stick to the rocks with a greaterpotential than any type of glue already created by man

mussels (mexilhões)


velcro


Arctium lappa, or spiny cocklebur, or velcro weed


Arctium lappa,or spiny cocklebur,

or velcro weed


VELCRO = velours + crochet [in French]

(velvet) (hook)

• invented by Georges de Mestral (Suisse) in 1941• patented in 1951

Georges de Mestral identified the principle used by this plant to spread its seeds (small hooks that grips to small

laces) and reproduced it in the velcro.

water flows accelerated through the shark skin reducing the friction

scales also inhibit the adherence of seaweed

It is formed by scales

shark skin

that give them hydrodynamic

vantages such as to reduce the turbulence while they swim


• material that is rigid without being brittle

• reduces the amount of ‘drag’ as the shark swims

• decreases the ‘friction’ of the water flowing along the shark 's body

• gets rid of parasites

• minimizes the area to which ‘organisms’ can adhere

• sharks ‘swims’ efficiently

Is covered with tiny scalesshark skin

• swim suits for competitions

• cover for the hull of the ships (ship design)

shark skin

also inspiration for:


• cover for the hull of the ships (ship design)save millions of dollars in fuel and cleaning costs.


• cover for the hull of the submarines too• for military airplanes too


Toyota claims that it improves gas mileage by 18-20%

• swim suits for competitions • cover for the hull of the ships (ship design) • cover for the hull of the submarines• military airplanes• cover for cars

shark skininspiration for:


� the low coefficient of drag helps the boxfish (peixe-cofre) to have a velocity equivalent to six times its length per second, using as stabilizers the edges of the shell in the form of keel.

tropical boxfish

� inspiration for:

Bionic Car from Mercedes Benz


tropical boxfish

� the air flow in a test on the wind tunnel proves that the car has an excellent aerodynamics

� it should give us some savings in fuel with consumption around 30 km per litter


tropical boxfish


� the Mercedes-Benz Bionic was a concept car introduced in USA in 2005 with better engine performance, stability and agility

� The exterior design was modelled after the yellow boxfish (Ostracion cubicus), a marine fish that lives in coral reefs.

Bioinformatics also uses analogies with situations in life and nature to solve human problems using ‘computer science’, such as for example:

system for natural

ventilation inspired in the termites


system for natural ventilation in the Eastgate Centre (Zimbabwe)

the first building in the world to use natural cooling to this level of sophistication
