Linx is the first fully integrated, microprocessor-controlled lower limb system for above-knee amputees. Combining four microprocessors and seven situational awareness sensors for control and balanced limb loading, the knee and ankle units communicate continuously to adjust resistance and speed for ease of use, safety and stability.
The knee unit shell, which contains the hydraulic chamber, sensors, electronics and battery, is made of carbon fiber. Individual sheets of pre-impregnated carbon fibre are layered by hand and cured in an autoclave, where the resins and carbon fiber are heated and pressure treated to form a tough, strong, lightweight outer shell.
The shin tube connecting the knee unit to the ankle/foot is aluminum.
The ankle unit, containing a hydraulic chamber and microprocessor, is constructed of aluminum and stainless steel. Connected to the ankle carrier are e-carbon foot springs. Developed by Endolite, the flexible yet strong carbon fiber foot springs provide strength and energy return. Foot springs are manufactured by layering sheets of pre-impregnated carbon fiber. The cured sheets are then cut with water jets to provide the various sizes of foot springs needed.
Linx was also named Best in Show of MDEA 2017.
