Abstract:
1. A method of harvesting vibrational energy comprising: generating a high magnetic flux density field within a current induction conductor, wherein the high magnetic flux density field is generated between two same pole magnets; displacing the high magnetic flux density field relative to the current induction conductor with vibrational energy; energizing the current induction conductor with displacements of the high magnetic flux density field relative to the current induction conductor; mechanically mounting the two same pole magnets between piezoelectric transducer (PZT) materials; generating a electrical potential across the PZT materials when the PZT materials are subject to the vibrational energy; and storing electrical energy translated from the vibrational energy through both the energized current induction conductor and mechanically stressed PZT materials.
