Abstract
Myoelectric control of a prosthetic limb is achieved by positioning a soft, flexible pad on the interior surface of a liner and embedding a large plurality of electrically conductive contacts within the pad. A window is cut in the liner to enable attachment of limb control electrodes to the pad. The pad has a low resistivity so that the individual contacts detect very low myoelectric signals. In a preferred embodiment, about forty thousand contacts, each of which is surrounded by non-conductive silicone, are positioned in a one inch square area. The number of signals produced enables the development of highly versatile prosthetic limbs.
