Biomimicry in Action: New Materials Inspired by Squid Skin for Camouflage
UPSC Relevance
Prelims: Science & Technology (Biomimicry, Camouflage, Nanotechnology, Material Science), General Science (Biology).
Mains: GS Paper 3 (Science and Technology- developments and their applications and effects in everyday life; Indigenization of technology and developing new technology).
Key Highlights from the News
Main Discovery: Researchers developed new artificial materials that can change color and transparency, inspired by the skin of squids.
Natural Model:
Squids get this ability from specialized cells called iridophores in their skin.
The unique structure within these cells controls light. This structure has a wave-like pattern in its refractive index.
Scientific Approach: This is an excellent example of biomimicry, a branch of science that solves human problems by learning from nature.
Possible Uses: These new materials can be used for camouflage, thermal control, advanced displays, and sensors.
