Touch Bionics have yet again produced an improved version of their flagship prosthetic hand, the i-Limb Ultra. Just like the previous i-Limb Pulse, it has five individually powered articulating fingers and manually rotatable thumb and wrist, plus exercising strength proportional to the input signal with pulsing for increased grip force.
On top of that the device incorporates a few tweaks such as variable grip strength for digits, improved software, and better power management. 
Here’s the full list of new features from the product page:
• Vari-grip allows variable digit-by-digit grip strength
• Gesture selection allows users to create custom gestures
• biosim-i (user) or biosim-pro (clinician) software allows selection of automatic hand modes, signal assessment, gestures and training modes.
• Two i-limb skin active coverings
• One i-limb skin natural covering
• Hand automatically moves to a natural position after period of inactivity
• Power management, extending daily battery usage by 25%
• Low battery warning audio signal
• 2-year standard warranty
There are a variety of skin coverings available for the prosthesis: first, i-limb skin active is a thin layer of semi-transparent, flesh colored or black material that has been computer-modeled to accurately wrap to every contour of the hand, designed for simplicity and ease of use. Second, the i-limb skin natural, a lifelike covering that gives a more cosmetic appearance, in one of ten different skin shades for both genders. Lastly, the i-limb skin match, the most realistic covering option possible, where the silicon skin is hand painted to exactly match the user’s skin tone and features (or a more creative, artistic design if you like). The new prosthetic hand was presented at the American Orthotic & Prosthetic Association National Assembly in Las Vegas.
