Some patients, mainly military personnel, particularly love the robotic nature of the uncovered i-LIMB Hand and prefer not to wear it with a cosmesis glove. However, because of the need to provide a grip surface and to protect the hand from dust and water, Touch Bionics has developed the i-LIMB Skin. This is a thin layer of semi-transparent material that has been computer-modeled to accurately wrap to every contour of the hand.
