1) Biomimetics and orthotics aim to take inspiration from nature to develop new technologies for assisting human movement and correcting physical limitations. 2) Nature provides many examples of structures and mechanisms that control motion, position body segments, and redirect forces, which can serve as models for orthotic design. 3) The development of biomimetic orthotics involves identifying gaps in current technologies, researching equivalent biological solutions, and generating new product ideas that are unique, cost-effective and sustainable.

- "[Franco] Lodato took as his model [for an ice axe] the woodpecker--a bird that chisels into wood to get at the insect larvae on which it feeds. Despite the bird's small size, it can manage 25 hits a second, with a surprisingly forceful impact. Studying the woodpecker's biomechanics further, Lodato found that its body is designed specifically for this movement. Woodpeckers brace themselves with their tails, which function as springs, taking advantage of both their center of gravity and their skull-bone configuration to absorb considerable stress. In other words, the birds did not hammer on the wood by using their necks. The finished axe consists of 'an inner core of titanium into which is inserted an adjustable aluminum point. These two parts are attached by a hinge inspired by the two valves of a mollusk. Special attention was dedicated to the shape of the handle. Rather than designing it to be straight, I incorporated into it a slight curve, again taking the body of the woodpecker as a model. This improves the efficiency of the blow.'"

- In Maori culture, nature is the master strategist. Nature has always taught humankind. \nThe Maori are no different. The animals, the trees, the weather patterns, the waters and nature herself were all teachers of the warrior. In the wananga (school) of life, the sky is the roof, the earth is the floor and all life forms are teachers. Here are some examples.\n\n
- The Fern Frond. \nThe fern frond was used as a pattern to encircle, envelop and crush the enemy. It could be used as a tactical manoeuvre or a weaponry sequence. Look at the fern frond. Watch how it grows and spirals. Look at the small shoots. Notice the same patterns emerging. \n\nYou can apply the fern frond metaphor to a problem you may have. \nEncircle it from different directions. \nLook at it through different eyes. \nApproach it from different angles. \nUpside- down. Back to front. Inside-out. \nWatch a solution grow within your consciousness.\n\n

- "Thin walled cylindrical shell structures are widespread in nature: examples include porcupine quills, hedgehog spines and plant stems. All have an outer shell of almost fully dense material supported by a low density, cellular core. In nature, all are loaded in some combination of axial compression and bending: failure is typically by buckling. Natural structures are often optimized. Here we have investigated and characterized the morphology of several natural tubular structures. Mechanical models recently developed to analyze the elastic buckling of a thin cylindrical shell supported by a soft elastic core (G.N. Karam and L.J. Gibson, Elastic buckling of cylindrical shells with elastic cores, I: Analysis, submitted to Int. J. Solids Structures, 1994, G.N. Karam and L.J. Gibson, Elastic buckling of cylindrical shells with elastic cores, II: Experiments, submitted to Int. J. Solids Structures, 1994) were used to study the mechanical efficiency of these natural structures. It was found that natural structures are often more mechanically efficient than equivalent weight hollow cylinders. Biomimicking of natural cylindrical shell structures may offer the potential to increase the mechanical efficiency of engineering structures." (Karam and Gibson 1994:113)\n\n\n
