NASHVILLE, Nov. 8 (UPI) -- Recent technological advances promise artificial legs that emulate healthy limbs, mechanical engineers at Vanderbilt University in Nashville say.
Lithium-ion batteries that store more electricity, powerful brushless electric motors with rare-Earth magnets, miniaturized sensors built into semiconductor chips, particularly accelerometers and gyroscopes, and low-power computer chips make it possible to create prosthetics that can duplicate the natural movement of human legs, they said.
