The socket as the link between residual limb and prosthetic components is the crucial
part of the prosthesis influencing the amputee’s acceptance considerably.
In addition to protection from outside influences, the skin is responsible for regulating
the body temperature. As parts of the skin are missing due to amputation, this functionality
is minimized. This effect is increased by common liners consisting of silicone or
equivalent materials, covering the residual limb surface.
A new developed liner is made of spacer fabric in combination with partial silicon
coating for suspension. This way the functionality of the skin inside the socket is
supported to regulate temperature based on permeability to gas and humidity. The cushioning
effect of the liner reduces pressure peaks and shear forces to prevent skin breakdown.
The new approach of an interface design combines the comfort of using the conventional
liner technique with the support provided by natural skin functionality.
