Bio-mimetics

1
Bio-mimetics From Wikipedia, the free
encyclopedia Biomimetics (also known as
Bionics, biognosis, biomimicry or bionical
creativity engineering) is the application of
biological methods and systems found in nature to
the study and design of engineering systems and
modern technology "taking design ideas from
nature" Biomimetic refers to human-made
processes, materials, devices, or systems that
imitate nature. WHY NATURE ???????

• Functions Mechanisms
• Principles
• Almost all engineering could be thought of as a
  form of biomimicry ??

• Fabrication/Manufacturing The Natures Way.
• Supramolecular, hierarchical..
• Self-assembly (bottom-up) Self-organization.
• Processing conditions Wet and soft, room temp..
• Directed and coded

• Devices Machines
• Neuromorphic chips, silicon retinae or coachleae
  wiring modeled after real neural network
  connectivity functionality
• Molecular motors

Bio-inspired Nanomotors Machine
In 1959 Feynman gave his famous after-dinner talk
describing molecular machines building with
atomic precision There's Plenty of Room at the

The portal motor for bacteriophage f29
compresses the DNA 6,000 times its normal
volume," says Bustamante. "This generates an
internal pressure of about 60 atmospheres, which
is about ten times that in a champagne bottle.

• Principles
• Cybernatics
• Artificial intelligence
• Genetic algorithms
• Socio-political models
• Examples Bioregional Democracy
• (political borders conform to natural Eco-regions
  rather than human cultures or the outcomes of
  prior conflicts)
• Natural Capitalism
• (Biomimicry is also the second principle of
  Natural Capitalism)

Does Nature always do an optimized job?

Sub-optimality in Nature Diversity Many ways
to the same function Complexity Many things to
be weighted

The field of Bio-mimetics is the abstraction of a
GOOD design from nature. Bio-inspired???
