Inventor of artificial hand sees 'bionic' replacement parts becoming more human
NEW BRUNSWICK/PISCATAWAY, N.J. Bionic limb replacements that look and work exactly like the real thing will likely remain a Hollywood fantasy, but fast advances in human-to-machine communication and miniaturization could bring the technology close within a decade.
