Biomimicry: How Nature Inspires Creative & Urban Design Solutions?

Feature image for blog post on role of Biomimicry in circular economy.

Introduction

Since the 19th-century Industrial Revolution, major economic systems have pursued aggressive consumption strategies, exploiting nature and its resources to extract raw materials and discard them after large-scale use. These practices have resulted in the accumulation of toxic waste and pollutants, while also disrupting critical ecological cycles. The consequences, including climate change and global warming, underscore the need for new economic models, prompting humanity to reconsider some of its fundamental methods and explore innovative solutions to adapt and synchronize with natural systems. Biomimicry, inspired by the designs and processes found in nature, emerges as a promising model to address these challenges.

Biomimicry: Learning From Nature

The study of nature has long been a foundation for human creativity and innovation, influencing ancient art and science alike. Inventors, artists, architects, and scientists have drawn inspiration from natural patterns, structures, and processes to solve complex problems and create groundbreaking works. Historical examples include Leonardo da Vinci, who studied bird flight to inform his designs for flying machines, and the Wright Brothers, whose first airplane is said to be modeled on pigeons. The Fibonacci sequence and the golden ratio, both rooted in nature, have guided art, architecture, and design for centuries.

An interesting story comes from Friedrich August Kekulé, the scientist who discovered the ring structure of the benzene molecule. According to his account, he dreamt of a snake biting its tail, forming a circular shape—a vision reminiscent of the ancient Ouroboros symbol. This symbol, rooted in cultural depictions of natural observation, highlights the deep interconnection between nature, art, science, and human knowledge.

What Is Biomimicry?

Biomimicry embodies a humble approach to studying nature, drawing inspiration from its designs and processes to solve human challenges. It integrates a blend of scientific disciplines, including biology, physical sciences, chemistry, design, and art, fostering innovation across various fields. The concept has been explored extensively in both science and fiction, influencing advancements in bionics and inspiring the idea of the cyborg—a fusion of biological and technological elements. This approach has already achieved remarkable success through the integration of technology to enhance biological functions, improving strength, boosting performance, and increasing adaptability, reusability, and longevity. By emulating nature’s principles, biomimicry offers transformative solutions that bridge the gap between natural and engineered systems.

Biomimicry spans a diverse range of fields and applications, offering innovative solutions to complex challenges. It is used in architecture to create energy-efficient buildings inspired by natural structures like termite mounds, which regulate temperature naturally. In medicine, biomimicry has led to advancements such as Velcro, modeled after the hooks of burdock burrs, and surgical adhesives inspired by the stickiness of gecko feet. Additionally, it influences robotics and engineering, with designs mimicking animal movements to improve functionality. By emulating nature’s time-tested strategies, biomimicry continues to transform industries and drive sustainable innovation.

Examples Of Biomimicry

1. Locomotion and Mobility

  • Trains: The Shinkansen bullet train in Japan faced noise issues due to tunnel pressure waves. Engineers solved this by redesigning the train’s nose after the kingfisher’s beak, which allows the bird to dive into water with minimal splash. This biomimetic design reduced noise and increased energy efficiency.
  • Kangaroo Robots: Inspired by the efficient hopping of kangaroos, researchers have developed robots that mimic this form of locomotion. These kangaroo robots can store and release energy in their tendons, similar to the animal, allowing for energy-efficient movement.
  • Wing Design: The study of bird wings has significantly influenced aircraft wing design. For instance, the Wright brothers observed pigeons to understand wing-warping, leading to the development of controlled flight.

2. Flying Robots

Hummingbirds are known for their agility and ability to hover. Researchers have developed flying robots that replicate hummingbird flight mechanics, enhancing maneuverability in drones. These bio-inspired robots can navigate complex environments, making them useful for search and rescue missions.

3. Adhesives

Geckos can effortlessly climb vertical surfaces due to microscopic hairs on their feet called setae. This mechanism has inspired the development of synthetic adhesives that mimic gecko feet, leading to the creation of “gecko tape.” This adhesive is strong, reusable, and leaves no residue, with potential applications in robotics and manufacturing.

4. Architecture

Termite mounds maintain constant internal temperatures despite external fluctuations. This natural cooling system inspired the design of the Eastgate Centre in Harare, Zimbabwe. The building uses passive cooling techniques modeled after termite mounds, reducing the need for conventional air conditioning and saving energy.

5. Design

The lotus leaf’s surface is extremely water-repellent due to its microstructure, causing water to bead up and roll off, taking dirt with it. This “lotus effect” has inspired the development of self-cleaning surfaces and materials in textiles and paints, leading to products that require less cleaning and are more resistant to water and dirt.

Conclusion

Biomimicry offers a promising avenue by positioning nature as a mentor rather than a resource to be exploited. It opens a vast field of wisdom, scientific insights, and untapped secrets waiting to be discovered and applied. By synchronizing human design systems with intelligent natural designs and ecological science, biomimicry has the potential to create a more sustainable economic model.

This approach promotes a better flow of energy and materials within human economies, reducing emissions, pollution, and waste while enhancing the biodegradability of products. Ultimately, it fosters the harmonious integration of human activities into ecological systems, supporting a balanced and sustainable relationship with the environment.
