Biomimicry: Nature-Inspired Sustainable Design Solutions

Nearly everything we use today draws inspiration from nature, imitated from organic forms, patterns, and systems in the natural world. You’ll find adhesive bandages, airplanes, trains, and the Eiffel Tower inspired by the human femur bone. Removing a bandage can cause excruciating pain, yet the smallest amount of wetness can destroy its adhesive. Michigan Tech biomedical engineering professor, Bruce P. Lee, got his idea of smart adhesives from a foamy glue secreted by freshwater mussels to help them cement their "beard" onto rocky shores, boats, and docks. This is what biomimicry is all about. Nature offers incredible sources of inspiration in a world where the need for sustainable solutions has never been more critical.

Derived from the Greek word 'bio' referring to life and 'mimicry' denoting imitation, biomimicry means imitating life and nature—a concept applicable today across various fields, including engineering, materials science, and architecture. Also known as biomimetic or bio-inspired design, biomimicry takes from nature's engineering brilliance to solve some of the world's most pressing problems. Here is everything you need to know about biomimicry, its relevance in sustainable design, and the benefits of adopting nature-inspired solutions.

The principles of biomimicry

The three core principles of biomimicry, Emulate, Ethos, and Reconnect - form the foundation of this innovative and sustainable design philosophy.

Emulate

This principle encourages designers to observe and understand nature's strategies, forms, and processes and then apply that knowledge to create innovative human-made solutions. Believe it or not, nature has gone through millions of years of trial and error, refining its designs to achieve efficiency and resilience. By mimicking these natural models, designers can harness the power of evolution and adapt nature's solutions to human needs and challenges.

For example, Swiss engineer George de Mestral was inspired by burdock burrs sticking to his clothes and his dog's fur during a walk. This led him to invent Velcro, a hook-and-loop fastening system, which has since been used in various applications, including clothing, aerospace, and medical devices. The front-end design of Japan's Shinkansen bullet trains was redesigned based on the kingfisher's beak shape, which reduces noise, increases aerodynamics, and leads to faster, more energy-efficient trains. These examples show how biomimicry can lead to practical and elegant solutions that improve how we live and interact with our environment.

Ethos

The principle of ethos embodies the ethical responsibility of designers to prioritize sustainability, regenerative practices, and the well-being of humans and the natural world. Instead of focusing solely on short-term gains, biomimicry encourages designers to consider the long-term impacts of their creations on the environment, society, and future generations.

By adopting the ethos principle, designers seek to create products and systems that support ecological health, reduce waste, conserve resources, and contribute positively to the ecosystem. This mindset aligns design practices with the broader environmental balance and social responsibility goals.

Reconnect

Many people have become disconnected from the natural world in a rapidly urbanizing and technology-driven world. This leads to a lack of understanding and appreciation for the intricate relationships and interdependencies that sustain life on Earth. The reconnect principle emphasizes fostering a deeper connection with nature. Biomimicry inspires designers to actively engage with nature, learn from its processes and systems, and develop a sense of awe and respect for the natural world. Such reconnection can lead to a more profound understanding of the complex web of life, influencing designers to create solutions that work in harmony with the environment rather than against it.

By combining these three principles, biomimicry transcends the superficial aspects of aesthetics and appearance. Instead, it delves into the functional elements of nature's designs, seeking to understand the underlying mechanisms that make them super-efficient and well-adapted. Learning from nature's brilliance inspires the development of optimized, sustainable, innovative solutions that meet human needs and contribute to the planet's health and vitality.

Biomimicry transcends appearances and focuses on functional aspects that acknowledge nature's designs are honed over millions of years of evolution. It encourages a more conscious and harmonious relationship between humans and nature for a more sustainable and regenerative future.

The two main approaches to biomimicry

Problem-based and solution-based are the two main approaches to biomimicry that differ in their starting points and methodologies:

Problem-based approach

The design process in this approach begins by identifying a specific environmental or technological challenge that needs addressing. This issue could be related to sustainability, resource efficiency, pollution reduction, or any other problem faced by human systems. Once the problem is defined, biomimicry designers or researchers turn to nature to study various organisms, ecosystems, and processes that have already evolved effective strategies to tackle the identified challenge.

They carefully study the mechanisms, structures, and processes nature has developed through millions of years of evolution. Designers then apply these solutions' principles to human-made technologies or systems. A problem-based biomimicry project, for example, might involve making buildings more energy-efficient in hot climates. Researchers would study how desert organisms, like certain plants or animals, have adapted to survive in extreme heat and manage water efficiently. Emulating these natural strategies could help create buildings that maintain a comfortable temperature while minimizing energy consumption.

Solution-based approach

Conversely, the solution-based approach starts by observing and understanding existing natural adaptations and designs. Rather than targeting a specific problem at the outset, designers explore the vast array of biological organisms and ecosystems to discover inspiring and elegant solutions that have already evolved in nature.

By observing nature's inventions, designers gain insights into how organisms have successfully solved challenges over time. They examine biological structures, processes, and behaviors to identify potential applications in human technologies or systems. This open-ended approach can lead to unexpected and innovative solutions to various problems.

For instance, the solution-based approach might consist of studying sharkskin's morphology to understand how it decreases drag in the water. This knowledge could inspire the creation of more efficient transportation methods with reduced aerodynamic resistance.

In biomimicry, the problem-based approach starts with a specific challenge and search for nature-inspired solutions. The solution-based system draws inspiration directly from nature's adaptations and designs to improve existing technology or solve problems. In a nutshell, both approaches provide valuable perspectives and tools for designers and innovators eager to harness nature's wisdom to create sustainable and efficient solutions for the future. They offer unique views on harnessing nature's wisdom for revolution and sustainability.

Examples of biomimetic design

So far, you know that biomimicry looks to nature's time-tested strategies, patterns, and processes to create sustainable solutions for human challenges. These solutions can be applied to various fields and industries that have embraced biomimetic options, which have led to pioneering innovations in sustainable design. In architecture, for example, biomimicry has given rise to buildings that mimic the thermoregulatory properties of termite mounds, resulting in significant energy savings.

Researchers in transportation have drawn inspiration from the streamlined shape of birds and fish to create more aerodynamic vehicles or aircraft that help mitigate excessive fuel consumption and emissions. Energy is not left behind—nature's photosynthesis has influenced the development of more efficient solar panels. As aforementioned, burdock burrs inspired Velcro design, and bullet trains took their inspiration from the kingfisher's beak shape. But did you know the wind turbine blade design was copied from humpback whales? Known for their elaborate displays, humpback whales have unique tubercles on the edge of their flippers, which reduce drag and increase lift. This biomimetic phenomenon has been applied to wind turbine blade designs to make them more efficient and quieter.

The lotus leaf has a unique nanostructured surface that repels water and self-cleans when rainwater washes away dirt. This concept has been applied in materials science to inspire the development of super-hydrophobic coatings for various materials, leading to self-cleaning surfaces and water-resistant products.
