An object of the invention is to provide a cheap, efficient and polyvalent energy harvesting system able to exploit several energy sources. The invention proposes an energy harvesting system () including a frame, at least one permanent magnet () having a North/South direction, and at least one winding () wound according to a winding direction around a core (-) including a high magnetic permeability material, at least said at least one permanent magnet being mounted on the frame to be able to oscillate relatively to the winding, characterized in that the system includes a magnetic flux divider arranged between said at least one permanent magnet and said at least one winding in order to concentrate the magnetic flux at discrete positions of maximum magnetic flux then forming equilibrium positions where the winding faces one of the said discrete positions of maximum magnetic flux.
