Abstract: The present disclosure provides for improved systems, apparatus and methods whereby electrical energy may be generated by the action of the user of the apparatus while, for example, walking, running or other activity that places the user's weight alternately on each heel and/or toe in sequence.

Abstract: An apparatus and a method are provided for obtaining electrical power from activities, e.g., walking and running, of a user. In one example, the apparatus includes first and second compressible bladders; a fluid containing column coupled between the first and second compressible bladders; a magnetic piston disposed in the fluid containing column, the magnetic piston being shaped to conform with an internal cross section of the cylinder and movable in the cylinder along a longitudinal direction of the cylinder, wherein the magnetic piston comprises a plurality of magnets with similar poles facing each other and separated by one or more pole pieces, the magnets being axially magnetized along the longitudinal direction; one or more wire windings disposed proximate the magnetic piston; and an electric charge storage electrically coupled to said one or more wire windings.
