Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from Ancient Greek: βίος (bios), life, and μίμησις (mīmēsis), imitation, from μιμεῖσθαι (mīmeisthai), to imitate, from μῖμος (mimos), actor. A closely related field is bionics.
Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. Biomechanics is a branch of biophysics.
Janine M. Benyus is an American natural sciences writer, innovation consultant, and author. After writing books on wildlife and animal behavior, she coined the term Biomimicry to describe intentional problem-solving design inspired by nature. Her book Biomimicry (1997) attracted widespread attention from businesspeople in design, architecture, and engineering as well as from scientists. Benyus argues that by following biomimetic approaches, designers can develop products that will perform better, be less expansive, use less energy, and leave companies less open to legal risk.
Bionics or biologically inspired engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology. Given that the subject is one that has only emerged very recently, bionanotechnology and nanobiotechnology serve as blanket terms for various related technologies.
The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface. Ultrahydrophobicity and self-cleaning properties are also found in other plants, such as Tropaeolum (nasturtium), Opuntia, Alchemilla, cane, and also on the wings of certain insects.
The Max Planck Institute of Colloids and Interfaces is located in Potsdam-Golm Science Park in Golm, Potsdam, Germany. It was founded in 1990 as a successor of the Institute for Physical Chemistry and for Organic Chemistry, both in Berlin-Adlershof, and for Polymer Chemistry in Teltow. In 1999, it transferred to newly constructed extension facilities in Golm. It is one of 80 institutes in the Max Planck Society (Max-Planck-Gesellschaft).
Biomimetic materials are materials developed using inspiration from nature. This may be useful in the design of composite materials. Natural structures have inspired and innovated human creations. Notable examples of these natural structures include: honeycomb structure of the beehive, strength of spider silks, bird flight mechanics, and shark skin water repellency. The etymological roots of the neologism "biomimetic" derive from Greek, since bios means "life" and mimetikos means "imitative".
The Biomimicry Institute is a 501(c)(3) not-for-profit organization founded in 2006 and based in Missoula, Montana in the United States. Its goal is to help innovators learn from nature in order to design sustainable products, processes, and policies in response to real-world problems. The Biomimicry Institute has become a key communicator in the field of biomimetics, connecting thousands of practitioners and organizations across the world. Its Global Network currently supports 38 regional networks across 26 countries as of 2022. The Biomimicry Institute was founded by Bryony Schwan, Dayna Baumeister and Janine Benyus and originated following the publishing of Biomimicry: Innovation Inspired by Nature by Janine Benyus; a natural sciences writer, innovation consultant and author.
Bio-inspired robotic locomotion is a fairly new subcategory of bio-inspired design. It is about learning concepts from nature and applying them to the design of real-world engineered systems. More specifically, this field is about making robots that are inspired by biological systems, including Biomimicry. Biomimicry is copying from nature while bio-inspired design is learning from nature and making a mechanism that is simpler and more effective than the system observed in nature. Biomimicry has led to the development of a different branch of robotics called soft robotics. The biological systems have been optimized for specific tasks according to their habitat. However, they are multifunctional and are not designed for only one specific functionality. Bio-inspired robotics is about studying biological systems, and looking for the mechanisms that may solve a problem in the engineering field. The designer should then try to simplify and enhance that mechanism for the specific task of interest. Bio-inspired roboticists are usually interested in biosensors, bioactuators, or biomaterials. Most of the robots have some type of locomotion system. Thus, in this article different modes of animal locomotion and few examples of the corresponding bio-inspired robots are introduced.
The tubercle effect is a phenomenon where tubercles or large 'bumps' on the leading edge of an airfoil can improve its aerodynamics. The effect, while already discovered, was analyzed extensively by Frank E. Fish et al in the early 2000 onwards. The tubercle effect works by channeling flow over the airfoil into more narrow streams, creating higher velocities. Another side effect of these channels is the reduction of flow moving over the wingtip and resulting in less parasitic drag due to wingtip vortices. Using computational modeling, it was determined that the presence of tubercles produces a delay in the angle of attack until stall, thereby increasing maximum lift and decreasing drag. Fish first discovered this effect when looking at the fins of humpback whales. These whales are the only known organisms to take advantage of the tubercle effect. It is believed that this effect allows them to be much more manoeuvrable in the water, allowing for easier capture of prey. The tubercles on their fins allow them to do aquatic maneuvers to catch their prey.
Biomimetic architecture is a branch of the new science of biomimicry defined and popularized by Janine Benyus in her 1997 book. Biomimicry refers to innovations inspired by nature as one which studies nature and then imitates or takes inspiration from its designs and processes to solve human problems. The book suggests looking at nature as a Model, Measure, and Mentor", suggesting that the main aim of biomimicry is sustainability.
The Salvinia effect describes the permanent stabilization of an air layer upon a hierarchically structured surface submerged in water. Based on biological models, biomimetic Salvinia-surfaces are used as drag reducing coatings (up to 30% reduction were previously measured on the first prototypes. When applied to a ship hull, the coating would allow the boat to float on an air-layer, reducing energy consumption and emissions. Such surfaces require an extremely water repellent super-hydrophobic surface and an elastic hairy structure in the millimeter range to entrap air while submerged. The Salvinia effect was discovered by the biologist and botanist Wilhelm Barthlott and his colleagues and has been investigated on several plants and animals since 2002. Publications and patents were published between 2006 and 2016. The best biological models are the floating ferns with highly sophisticated hierarchically structured hairy surfaces, and the back swimmers with a complex double structure of hairs and microvilli. Three of the ten known Salvinia species show a paradoxical chemical heterogeneity: hydrophilic hair tips, in addition to the super-hydrophobic plant surface, further stabilizing the air layer.
Bio-inspired photonics or bio-inspired optical materials are the application of biomimicry to the field of photonics. This differs slightly from biophotonics which is the study and manipulation of light to observe its interactions with biology. One area that inspiration may be drawn from is structural color, which allows color to appear as a result of the detailed material structure. Other inspiration can be drawn from both static and dynamic camouflage in animals like the chameleon or some cephalopods. Scientists have also been looking to recreate the ability to absorb light using molecules from various plants and microorganisms. Pulling from these heavily evolved constructs allows engineers to improve and optimize existing photonic technologies, whilst also solving existing problems within this field.

Bioinspired armor are materials that were inspired by the composition, and most importantly, the microstructures commonly found in nature’s natural defense mechanisms. These microstructures have been evolved by organisms to protect themselves from exterior forces, such as predatory attacks. These materials and their microstructures are optimized to withstand large forces. By taking inspiration from these materials we can design armor that has better penetration resistance and force dissipation properties than previously possible.
