I-Limb® quantum is the new standard for myo-electric prosthetic hands. The i-limb® quantum is the only upper limb prosthesis that can change grips with a simple gesture. Gesture control enables an automated grip to be accessed by moving the i-limb® quantum in one of four directions - it really is that simple.

Control Methods

Control Method

Gesture control
Enables an automated grip to be accessed by moving the i-limb™ quantum in one of four directions.

App control
Mobile app control is driven by our quick grips™ technology which provides instant access to 24 pre-programmed and 12 custom grip patterns, allowing huge versatility and flexibility in customising the hand for a variety of daily activities. Quick grips™ are accessible with a number of mobile devices, including the Apple Watch.

Muscle control
For the advanced user, triggers are specific muscle signals that are used to instruct an i-limb™ to activate a specific grip.

Proximity control - grip chips™
are small Bluetooth® enabled devices that allow users to enter any available grips simply by moving their i-limb™ device close to an object where a grip chip is placed.

Pre-Programmed Grips
There are 24 pre-programmed grips with the i-limb™ quantum.

My grips™
With the i-limb™ quantum, my grips™ allows users to customise up to 12 new grips that are specific to their individual lifestyle.


While the i-limb™ is extremely durable and crafted from the highest quality materials available, it is necessary to protect it from dirt, dust and moisture by wearing a specially made covering. At Touch Bionics, we understand that your i-limb™ hand is a very important aspect of your life and with this in mind, we have created coverings that are just as individual as our users are.

i-limb™ skin active
Many of our users love to show off the robotic look of their new prosthesis and choose to wear an i-limb™ skin active covering. These coverings are designed for simplicity and ease of use. They are made of a thin layer of semi-transparent, clear or black material that has been computer-modelled to accurately wrap around every contour of the hand.

i-limb™ skin active TS
Recently we introduced the i-limb™ skin active TS which is compatible with all touch screen devices by having a conductive tip on the index finger. Both i-limb™ skin active and active TS coverings come with a special slip coating on the inside and back for ease of taking them on and off the hand.

i-limb™ skin contours
These new coverings are made from a flexible silicone with added durability. Anatomically shaped to resemble a natural hand, they are available in colours Clear, Light & Tan.

i-limb™ skin natural
These lifelike silicone coverings are for those who want a more natural cosmetic appearance and are available in 18 different shades to reflect a broad variety of skin tones.

i-limb™ skin match
These hand-painted silicone coverings are designed to blend in seamlessly with a users lifestyle by being remarkably lifelike. Fully customised, exact colour and skin tone appearance are captured using our i-Pad based Colour Capture System which is then downloaded to our artists painting studio in Newburgh, New York.
