This document provides an overview of biomimicry, which is modeling design after nature. It defines biomimicry as the design and production of materials, structures, and systems inspired by biological entities and processes. Examples given include shark skin which reduces drag for speed and prevents parasites, and termite mounds which use tunnels and chimneys for cooling. The document explains that biomimicry is important as it allows designs that function sustainably like the natural world, after 3.8 billion years of evolution. It promotes a circular economy with no waste. Future applications discussed include an artificial leaf that mimics photosynthesis for sustainable energy, and a flexible material inspired by dragonfly skeletons.
