Abstract:
1. A power generator comprising: a first array of magnets positioned on a planar surface, wherein the first array comprises a one dimensional or two dimensional array of magnets, wherein the first array of magnets comprises a sheet magnet with stripes of alternating magnetic poles; a serpentine conductor, wherein the serpentine conductor is on a plurality of layers of a multilayer printed circuit board, wherein the serpentine conductor comprises a first plurality of serpentines wired in series on a single layer of the multilayer printed circuit board, wherein a serpentine of the first plurality of serpentines wired in series comprises a first conductor running parallel to a magnetic stripe coupled to a second conductor running across the same magnetic stripe, and the second conductor coupled to a third conductor running parallel to the same magnetic stripe, and the third conductor coupled to a fourth conductor running across an adjacent magnetic stripe, wherein the second conductor and fourth conductor running across the magnetic stripe is shorter than the first conductor and the third conductor running parallel to the magnetic stripe, wherein the adjacent magnetic stripe is of a different magnetic orientation; and a power management circuit, wherein the power management circuit provides DC power as a result of relative motion between the first array of magnets and the serpentine conductor, wherein the DC power comprises an average power of less than 200 mW over a period of 20 mSec, and wherein the relative motion has a resonant frequency of less than 200 Hz.
