Abstract

In this study, we present the conceptual design of a fully-passive transfemoral prosthesis. The proposed design is inspired by the analysis of the musculo-skeletal activity of the healthy human leg. In order to realize an energy efficient device, we introduce three storage elements, which are responsible of the energetic coupling between the knee and the ankle joints. Simulation results show that the power storage of the designed conceptual prosthesis is comparable with the human gait.
