Touch Bionics calls the i-limb Ultra Revolution, "the most advanced and versatile prosthesis available," and says it, "offers more dexterity and moves more like a natural hand than any other powered prosthetic hand."
The i-limb was launched in 2007 and was the world's first fully articulating and commercially available bionic hand. The Ultra Revolution followed last year and is used, amongst others, by social psychologist Dr. Bertolt Meyer, who last year presented a TV program looking at state-of-the-art artificial limbs, organs and blood.
The Ultra Revolution allows users to program a number of primary grip types into it that can be triggered by different muscle movements. These will generally be the grip types that the user most often uses. The recent upgrades to the Ultra Revolution focus on increasing grip adaptability.
