Signal Processing in Next-Generation Prosthetics [Special Reports]

Artificial devices that allow amputees to either walk again or to continue to use an arm and hand have existed since ancient times, the most notable example being the simple peg leg. Modern prosthetics, however, are a world apart from predigital-age artificial limbs.

Using advanced robotic, cybernetic, and fabrication technologies, as well as signal processing, researchers are well on their way to making prosthetics that are remarkably useful, realistic, and intuitive.
