This paper presents a design and optimization of the fully-active transfemoral prosthesis leg system. As it has one degree of freedom in knee joint, this artificail leg can mimic the human’s gait. As the weight of leg is one of major factors, the mechanism of prosthesis is change from 3-linkage type to geared type. The sensorized foot is also designed to effectively determine human’s gait by measuring deformation of the foot during gait. Topology optimization is carried out for the sensorized foot to remove its unnecessary weight. The safety of optimized foot is verified by carrying out finite element analysis.
