Patent ID: 8907505

Claim:
An electrical energy generating apparatus in combination with a footwear, the apparatus comprising: a liquid containing assembly comprising: a first compressible liquid-filled cavity, a second compressible liquid-filled cavity, a first connecting and conducting tube connected at its first end to the first compressible liquid-filled cavity allowing liquid flow from and to the first compressible liquid-filled cavity, the first connecting and conducting tube being liquid filled, a second connecting and conducting tube connected at its first end to the second compressible liquid-filled cavity allowing liquid flow from and to the second compressible liquid-filled cavity, the second connecting and conducting tube being liquid filled, a liquid-filled cylinder, a first sealing component, sealing the first end of the cylinder having a hollow connection point connected to the second end of the first connecting and conducting tube allowing the liquid to flow from and to the first connecting and conducting tube, a second sealing component, sealing the second end of the cylinder having a hollow connection point that is connected to the second end of the second connecting and conducting tube that allows liquid to flow from and to the second connecting and conducting tube, an electrical generation assembly comprising: a wearable piston disposed in a sole of the footwear, and shaped to conform to the internal cross sectional shape of the cylinder, within the cylinder, free to move in a longitudinal direction along the cylinder, the piston comprising 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 electrically conductive insulated wire windings placed within the magnetic field of the piston and wound in alternate clockwise and anticlockwise directions and connected in series; and one or more electrical components electrically connected to the windings.
