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.”

Examples:
Bioregional Democracy

(political borders conform to natural Eco

regions rather than human
cultures or the outcomes of prior conflicts)

Biomimicry is also the second principle of
Natural Capitalism
)

Complexity:
