Abstract

A power generator comprises a first array of magnets or a first sheet magnet, a first conductor, and a power management circuit. The first array comprises a one dimensional or two dimensional array of magnets. The first sheet magnet includes a one dimensional or two dimensional array of alternating magnetic poles. The first conductor comprises a first serpentine conductor that is on a plurality of layers of a first multilayer printed circuit board or a first serpentine conductor that is on one or more planes. The power management circuit provides DC power as a result of relative motion between the first array of magnets or the first sheet magnet and the first conductor
