“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.

Bionic Systems
popular definition
bionics n.
the study and the construction of systems that function like (parts of) living beings.

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.
Bio-inspired systems______________________________________________________________________________________________________________________________________________________________________________________
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?”
Bio-inspired systems______________________________________________________________________________________________________________________________________________________________________________________
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
Bio-inspired systems______________________________________________________________________________________________________________________________________________________________________________________
even under the water, they stick to the rocks with a greaterpotential than any type of glue already created by man

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
Bio-inspired systems______________________________________________________________________________________________________________________________________________________________________________________
• 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

� 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.

� 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

� 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:
