1. An Energy harvesting device for converting a vertical force of a vertical motion to electricity, comprising:
a free to rotate push magnet that is fixed by a hinge to a body of the energy harvesting device,
a moving magnet that is designed to be vertically pushed from a first position to a second position when the vertical force is applied on the moving magnet,
a push back magnet that is fixed to the body of the harvesting device, and
a coil;
wherein when the vertical force is applied on the moving magnet the moving magnet moves from said first position to said second position and when the moving magnet moves from said first positon to said second position a repulsive magnetic force of the moving magnet rotates the push magnet, wherein rotation of the push magnet causes current in the coil;
wherein the push back magnet is designed to displace the moving magnet from said second position to said first position when the vertical force is stopped to be applied on the moving magnet; and wherein the push back magnet is designed to rotates backward the push magnet while the moving magnet is displaced to said first position.
