While studying the history of some inventions, I learned fascinating facts about how technology has been derived from nature. The majority of groundbreaking innovations were directly inspired by the unique abilities of animals. By observing these adaptations, scientists and engineers have developed some of the most significant technologies we use today. In this article, we will observe how certain inventions were made possible because of learning from animal adaptations.
1. Radar System – Bats and Owls as Inspirations
Bats use echolocation to fly in the dark – they send out sound waves that rebound off things and come back with information on shape and distance. Robert Watson-Watt, a British engineer, had been inspired by the principles of echolocation used by bats when he built the first operational radar in 1935. Later, scientists even studied the hearing of owls, capable of pinpointing prey accurately because of their sensitive hearing to sound. These same principles are utilized today in modern radar systems for tracking aircraft, ships, and cars.

2. Sonar – Dolphins and Whales' Inspiration
Dolphins and whales use biosonar to locate prey and navigate through murky waters. This discovery led to the development of artificial sonar, which is used today in underwater navigation, oceanic exploration, and detection of submarines. Researchers developed the first functional sonar back in World War I when they were aided by a necessity to detect enemy submarines.

3. Bullet Train Design – Kingfisher Inspiration.
Japan's Shinkansen bullet trains used to create severe sonic booms when coming out of tunnels due to the sudden air pressure differences. Engineer Eiji Nakatsu, an avid bird enthusiast, noticed that kingfishers could dive into water without producing a splash, due to the shape of the kingfisher's beak. He designed the nose of the train after the shape of the kingfisher's beak, reducing noise and increasing efficiency.
4. Anti-Bacterial Coatings – Shark Skin Inspired
Sharks have specialized skin with tiny denticles that reduce water resistance and prevent the growth of algae and bacteria. Their innate filtration system was employed as motivation to develop antibacterial coatings for vessels and medical equipment, reducing the transmission of harmful microbes.
5. Self-Cleaning Surfaces – Drawn from the Lotus Leaf
Lotus leaves have a certain surface pattern which is both water-repelling and dirt-repelling. Researchers have found this phenomenon, the so-called "Lotus Effect," and employed it to create self-cleaning paint, glass, and fabric that is waterproof as well as stain-repellent.

6. Artificial Limbs – Patterned Following Octopus Tentacles
Octopuses possess soft boneless arms that allow them to grasp and move objects gently. This has motivated researchers to develop soft robot arms and prosthetics with better flexibility and capacity to adapt compared to conventional artificial limbs.
7. Drones – Inspired by Insects and Birds
Scientists watched birds and insects fly in the sky to design quicker and steadier drones. Imitating the wings' flapping of birds and the bees' ability to hover, drone control and effectiveness were improved by engineers.
8. Camouflage Technology – Chameleons and Cuttlefish inspired
Cuttlefish and chameleons can change the color of their skin to blend with the environment as a result of specialized cells known as chromatophores. Scientists have developed adaptive camouflage technologies and garments that shift their color based on the environment, which has applications in military and stealth technology.

9. Ventilation Systems – Termite Mound Inspired
Termite mounds have a natural ventilation system that keeps the inside of them cool even when there is heat outside. Engineers applied these concepts to modern buildings, designing energy-conserving structures with better airflow and temperature regulation.
10. Adhesive Technologies – Gecko Feet
Geckos are capable of wall-climbing and ceiling-climbing due to the presence of microscopic protrusions on their feet, which form very strong adhesive forces. It led to developing man-made adhesives in the form of dry glues and robot/climbing technologies for space applications.

In the end
The animal kingdom itself has limitless possibilities for innovation. From sonar and radar to trains and medical supplies, nature is generally the place to look for technological inspiration. By studying and understanding the adaptations of animals, scientists have been able to create inventions that have shaped the world today. In future years, we may increasingly rely on nature to solve new problems!
