Innovations inspired by Nature

1) Airplane inspired by Birds


When the Wright brothers were figuring out how to build an airplane, they took inspiration from some of the fliers of the natural world – birds.

Nature has had a long time to perfect its ways so do the Innovations.

2) The Bulletproof vest inspired by spider silk


The bulletproof vests that are used currently are made from artificial fiber known as Kevlar. However, nature has a stronger replacement for this fiber, which is none other than spider silk.

The silk is also highly elastic and can stretch 40% longer than its original length. After several trial and errors on the spider web-based material, scientists intend to use the same for making artificial ligaments, suspension bridges, parachutes

3) Bionic car is inspired from a Box fish


The ace car manufacturer Mercedes benz’s new design, the Bionic car is inspired from a fish. The car is inspired by boxfish, a fish that lives in coral reefs, lagoons, and seaweeds. The reason behind using the boxfish as an inspiration is that it uses least amount of energy to move, it is swift in its movement, and its rigid outer skin can sustain collisions. The body of the fish has a networked structure where the bones form plates that are interlinked with each other. These plates protect the fish from injuries, and this structure is identical to that of a car.

4) Bullet train inspired by Kingfisher


A high-speed train emerging from a tunnel generates a tremendous thunderclap due to the air pressure that builds up in front of the nose. In the 1990s Japanese engineer Eiji Nakatsu noticed that kingfishers could dive into the water with barely a splash. His design for the Shinkansen bullet train, based on the kingfisher beak, not only reduced the noise of the train but was also more aerodynamic, using less power and enabling higher speeds.

Modification requires in every creation for better efficiency.

5) Turbine blades inspired by Whale Flippers


The humpback whales owe their agility to a row of ridges (tubercles) on the front edge of their fins. Despite their size, these whales can swim up to speeds of 16.77 miles per hour. Called the tubercle effect, it markedly improves the aerodynamics of any airfoil by a significant amount. It leads to higher velocities by creating narrow streams of airflow and reduces drag by reducing airflow over the wing-tips.

6) Injection Needles Inspired by the Mosquito’s Proboscis


There is a reason why you do not feel the mosquito bite. The saliva that enters the bloodstream post the bite is what causes the itch. The proboscis of a mosquito is made of 7 different movable parts – two of which hold the skin in place, two other make the cut, and the central tube sucks in the blood. This mechanism removes any sensation of pain usually felt on piercing through the skin.

Scientists have managed to copy three of these parts to create a motorized needle. this motorized needle has two serrated tubes with a central straw. The tubes vibrate slightly to ease into the skin and the serrated edges minimize the surface area of contact. This mechanism drastically reduces the pain, which is felt when any traditional needle is poked through our skin.
