Analysis of Energy Harvesting in a New Prosthetic Foot Via Bond Graph Method

This paper proposes the application of the Energy Harvesting concept to quantify the energy potential of mechanical energy from the direct contact of a prothetic foot with the ground during walking. Dynamic system modeling was used via Bond Graph technique. As a result, the mathematical model can be considered stable due to the location of the poles and zeros. The values of the simulated results converge to the experimental results, demonstrating the consistency, stability and convergence of the model. Furthermore, the use of Bond Graph technique allowed to quantify the power in 75 W during walking.
