High(tech) Five

The prosthetic Cyberhand aims to be the world's first to provide senses for its user and to be "controlled using the efferent neural signals coming from the central nervous system." That means it'll be hardwired into the nervous system so the brain can prompt use of the limb. As Physorg.com reports, it includes six motors for movement, an opposable thumb, and "sensors for tension, force, joint angle, end stroke and contact." Right now, Cyberhand is just a prototype but clinical validation will begin in '06.
