Abstract (en)

[origin: WO2011139655A1] An apparatus for harvesting electrical power from mechanical energy is described. The apparatus includes: a flux path. The flux path includes: a magnetic material having a magnetic property that is a function of stress on the magnetic material; a first magnetically conductive material proximate the magnetic material; a magnet in the flux path, wherein a magnetomotive force of the magnet causes magnetic flux; and a component configured to transfer changes in load caused by an external source to the magnetic material.
