Abstract
An apparatus for harvesting energy from motion of a prosthetic limb, wherein the prosthetic limb has motion in at least one degree of freedom, may include a piston configured to receive an input motion and provide an output motion when a first motion in a degree of freedom of the prosthetic limb causes pressure and motion of hydraulic fluid. The apparatus may include an electromagnetic motor for converting mechanical energy of the output motion into corresponding electrical energy delivered to an electrical load and a variable-impedance energy harvesting circuit across terminals of the motor.
