Abstract

Over the 3.8 billion years since life is estimated to have begun to appear on Earth, evolution has
resolved many of nature’s challenges leading to lasting solutions with maximal performance using
minimal resources. Nature’s inventions have always inspired human achievement and have led to
effective algorithms, methods, materials, processes, structures, tools, mechanisms, and systems.
There are numerous examples of biomimetic successes including some that are simple copies of
nature, such as the use of fins for swimming. Other examples were inspired by biological capabil-
ities with greater complexity including the mastery of flying that became possible only after the
principles of aerodynamics were better understood. Some commercial implementations of biomi-
metics can be readily found in toy stores, where robotic toys are increasingly appearing and
behaving like living creatures. More substantial benefits of biomimetics include the development
of prosthetics that closely mimic real limbs as well as sensory-enhancing microchips that are being
used to interface with the brain to assist in hearing, seeing, and controlling instruments. In this book,
various aspects of the field of biomimetics are reviewed, examples of inspiring biological models
and practical applications of biomimetics are described, and challenges and potential directions of
the field are discussed.
