Made of lightweight plastics and strong, resilient metal alloys, the artificial legs that carried Fonyo across the continent were the fruits of years of research in the art/science of prosthetics.
Among its products are modern prostheses - highly sophisticated artificial parts that replace missing or defective parts of the body. Advances in this little-known profession are often imperceptible to most people, but not to those whose health, happiness, and productivity depend on their "spare parts." The concept of a person who is part-human, part-machine is moving from the realm of science fiction into our everyday world.
Like many endeavors at the leading edge of science, prosthetics is multidisciplinary. It borrows materials, methods, and specialists from medicine, electronics, computer science, anatomy, mechanical engineering, and materials science. With each research project and clinical trial of a new prosthesis, the art/science of prosthetics tries to come closer to replacing an
