10 Cutting-Edge Innovations Inspired by the Natural World

Biomimicry is the practice of drawing inspiration from nature to develop advanced technologies. Often, the most groundbreaking innovations are derived from the evolutionary wonders that have evolved over millions of years. Below are 10 contemporary inventions inspired by plants and animals.

1. VELCRO

Developed in the 1940s by Swiss engineer George de Mestral, VELCRO stands as one of the most iconic examples of biomimicry. During a hike, de Mestral observed how burdock burrs' hook-like design enabled them to cling to his dog's fur. Intrigued, he sought to replicate this mechanism to create a revolutionary clothing fastener.

By 1955, de Mestral had patented a “hook and loop” fastener, naming it VELCRO, a blend of the French terms for velvet (velours) and hook (crochet). 

2. Self-Cleaning Paint

Lotus plants are celebrated for their serene aquatic beauty and cultural symbolism of longevity, but they also possess a remarkable superhydrophobic quality. The leaves of the lotus plant are so effective at repelling water and dirt that this phenomenon was named the “lotus effect” in 1977.

In 1999, the German construction firm Sto introduced an exterior paint named Lotusan. Once dried, the paint's microtexture replicates the lotus leaf's surface, effectively repelling moisture and dirt from building exteriors.

3. Camouflage

Humans have adopted camouflage, a survival strategy used by species like the chameleon and the polar bear, as a defense mechanism, particularly in military and hunting contexts.

Camouflage is effective because it conceals the body's outline, as the human eye struggles to differentiate color patterns from a distance.

4. Solar Panels

Both solar panels and plant leaves capture energy from sunlight, but a team at Princeton University advanced biomimicry by incorporating folds into solar cells. These folds replicate the natural ridges of leaves, directing more light into the cells. In 2015, the team reported that these leaf-inspired cells produced 47 percent more electricity than flat ones.

5. Adhesive Climbing Gear

Gecko toes possess a remarkable ability to stick to almost any surface, even smooth glass. In 2014, researchers at Stanford University amplified the adhesive structures found in tokay gecko toes to develop a climbing device inspired by geckos. A human tester successfully scaled a glass wall using adhesive pads on their hands and feet.

6. Bullet Trains

Japan's Shinkansen Bullet Train is renowned for its aerodynamic design, which reduces noise when entering and exiting tunnels at speeds of 150 to 200 mph. The train's shape was inspired by the slender beak of the kingfisher, a bird that dives into water with minimal splash to catch fish. This design also enables the train to travel 10 percent faster while using about 15 percent less electricity. 

7. Airplanes

Although contemporary airplane engineering has advanced significantly from avian-inspired techniques, early models relied on the limited knowledge of flight derived from observing birds in their natural habitat.

For their pioneering manned plane, the Flyer, the Wright brothers replicated the way air enhances lift as it moves over the arched surface of bird wings. Birds adjust their wings to maintain altitude and optimize flight efficiency. Orville and Wilbur Wright designed the aircraft with a mechanism that allowed parts of the wings to flex, mimicking this avian capability.

8. Wetsuits

While whales rely on blubber for insulation in cold waters, beavers use their dense fur to trap air between the strands, providing warmth and dryness. Inspired by this natural adaptation, a team of engineers at MIT in 2016 developed a wetsuit featuring rubber “hairs” to replicate this effect, aimed at enhancing comfort for watersports enthusiasts such as surfers. The trapped air on the suit’s surface ensures warmth, much like it does for beavers.

9. Self-Cooling Architecture

Is the termite a nuisance or a source of inspiration? The answer varies. While termites are often seen as pests, some architects admire the natural cooling systems of their mounds.

Zimbabwean architect Mick Pearce studied a termite mound on a golf course, noting its efficient shape and ventilation. He applied this design to buildings in Harare, Zimbabwe, and Melbourne, Australia. These structures draw cool air from the ground and release warm air through chimneys at the top.

10. Needles

For those anxious about flu shots, a breakthrough in microneedle technology, inspired by the mosquito's proboscis, offers a nearly painless alternative. The insect’s ability to pierce skin swiftly and painlessly, aided by an anesthetic substance in its saliva, has led to the development of microneedles that replicate this gentle approach.
