A Valve-Less Electro-Hydrostatic Powered Prosthetic Foot to Improve the Power Efficiency During Walking

Hydraulic systems have been widely applied in lower-limb prostheses, primarily for their compact actuation and inherent damping capability. However, when applied to powered prosthetic feet, valves and other damping elements cause unavoidable energy dissipation, thereby constraining their power densi
