3. Introduction
• “Biomimetics” originates from the
Greek words “bios” (life) and
“mimesis” (to imitate)
• Biomimetics is the study of nature
and natural phenomena to
understand the principles of
underlying mechanisms, to obtain
ideas from nature, and to apply
concepts that may benefit science,
engineering, and medicine
