About 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 artificial limb 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 Prosthetic 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.

Learn more about i-LIMB Hand Grip Patterns:

  • Touch Bionics is utilizing the myoelectric principles used in existing devices while taking advantage of the mechanical advance of five fully-articulating powered digits.
  • The inclusion of a thumb that can, like the human thumb, be rotated into different positions enables important grip configurations, many of which have not been available to amputees before.
  • The grasp of the robotic hand is much more like that of a human hand with the articulating fingers able to close tightly around objects. Built-in stall detection tells each individual finger when it has sufficient grip on an object and, therefore, when to stop powering. Individual fingers lock into position until the patient triggers an open signal through a muscle signal.

Key Grip:

  • Where the thumb closes down onto the side of the index finger. This grip is used to hold items such as a plate or a business card. The addition of wrist rotation enables the patient to turn a key in a lock in a totally ‘human’ way.

Power Grip:

  • Where all fingers and the thumb close down together to create a full-wrap grip. This grip would be used to hold a can of drink whilst opening the ring-pull, for example, and for carrying large objects such as a briefcase and/or shopping bag.

Precision Grip:

  • Where the index finger and thumb meet (or index finger, middle finger and thumb meet) in order to pick-up small objects and to hold objects when performing finer control tasks.

Index Point:

  • Where the thumb and fingers close but the index finger remains extended – this is yet another first from Touch Bionics and very important in today’s modern world. Patients have found this grip very useful for operating computer keyboards, telephone dial pads, ATM cash machines and a host of other everyday requirements.
  • Feedback from early patient studies identified that software adjustments can allow patients to perform simple tasks and improve functionality. An example of this being ‘thumb parking’, instructing the thumb to close down against the side of the hand to allow a jacket to be put on.
