The i-LIMB Hand

The worlds first fully articulating and commercially available bionic hand.

Touch Bionics is a leading developer of advanced upper-limb prosthetics (ULP). One of the two products now commercially available from the company, the i-LIMB Hand, is a first-to-market prosthetic device with five individually powered digits. This replacement hand looks and acts like a real human hand and represents a generational advance in bionics and patient care.

The Touch Bionics i-LIMB Hand was developed using leading-edge mechanical engineering techniques and is manufactured using high-strength plastics. The result is a next-generation prosthetic device that is lightweight, robust and highly appealing to both patients and healthcare professionals.

The i-LIMB Hand is controlled by a unique, highly intuitive control system that uses a traditional two-input myoelectric (muscle signal) to open and close the hand’s life-like fingers. Myoelectric controls utilize the electrical signal generated by the muscles in the remaining portion of the patient’s limb. This signal is picked up by electrodes that sit on the surface of the skin. Existing users of basic myoelectric prosthetic hands are able to quickly adapt to the system and can master the device’s new functionality within minutes. For new patients, the i-LIMB Hand offers a prosthetic solution that has never before been available.

Advanced Design
The modular construction of the i-LIMB Hand means that each individually powered finger can be quickly removed by simply removing one screw. This means that a prosthetist can easily swap out fingers that require servicing and patients can return to their everyday lives after a short clinic visit. Traditional devices would have to be returned to the manufacturer, often leaving the patient without a hand for many weeks.

RAPHaEl, the air-powered robotic hand
Making ‘bionic hand’ history in prosthetics! May 13, 2009

The new ‘bionic hand‘ was created by the Robotics and Mechanisms Laboratory of the College of Engineering at Virginia Tech, and was named: ‘RAPHaEL’ – Robotic Air Powered Hand with Elastic Ligaments. The new ‘bionic’ robotic hand that can firmly hold objects as heavy as a can of food or as delicate as a raw egg, while dexterous enough to make hand gestures for sign language.
RAPHaEL is just part of a larger RoMeLa project: The humanoid robot known as CHARLI (Cognitive Humanoid Robot with Learning Intelligence). The hand already is on its second prototype design, with the newer model to be used by CHARLI. Once the newer model hand is connected to the larger body, it will be able to pick up – not just grasp and hold – objects as would a person.
