    Abstract: A method for achieving a desired vibration resonance frequency of electromagnetic energy harvesters that includes the step of providing a harvester that includes a coil wound along a core, a magnet, a suspending device that includes a base connected to the body and a hinge connected to the magnet, and a stationary magnet attached to the body or the base when the positive poles of the magnets faces each other and the repulsive magnetic force between them restore the magnet. The gravity center of the hinge and the magnet is shifted off the rotation axis of the hinge so that body vibrations cause a relative alternating movement between the core and the magnet that creates alternating voltage between in the coil, and the step of determining the specific distance between the magnets based on the magnetic flux strength of the stationary magnet for achieving the desired frequency.

    Abstract: An electromagnetic energy harvesting system for converting kinetic excitations of a body to electricity. The system includes a coil, a magnet, and a push-back magnet that is fixed to the body. The magnet is connected to the body by an axial connection that enables the magnet to rotate about the axis of rotation that is distal from the center of gravity of the magnet. The push-back magnet exerts repulsive force on the magnet rotates the magnet about its axis of rotation in a way that the center of gravity of the magnet rotates away from the push-back magnet. The kinetic excitations of the body cause the magnet to rotate about its axis of rotation in a way that the center of gravity of the magnet rotates towards the push-back magnet, and as a result the rotations of the magnet create alternating voltage between ends of the coil.

    Abstract: A harvesting system that includes a dynamo with a rotor and a stator, a push magnet that is attached to the rotor or is a part of it, a moving magnet that moves from a first position to a second position, and a push back magnet. The repulsive magnetic force that is exerted by the moving magnet on the push magnet in the second position is greater than that force in the first position. The moving magnet moves from the first position to the second position and causes the rotor to rotate from a dynamo first position to a dynamo second position that causes the dynamo to produce current. When the moving magnet moves back to the first position the dynamo returns to its first position due to magnetic force that the push back magnet exerts on the push magnet.

    Abstract: A device for converting bends of a body to electricity that includes a generator, a bending converter and a connector. The generator includes a stator and a rotor that is connected to a rotational shaft. The bending converter includes a bending arm that has a front side and a back side. The stator and the back side of the bending arm are designed to be fixed directly or indirectly to the body. The rotational shaft is connected to the connector at a first connecting point and the front side of the bending arm is connected to the connector at a second connecting point. When the body bends then the bending arm bend and rotates the rotor relative to the stator.

    Abstract: An electromagnetic energy harvester for converting vibrations of a body to electricity that includes a coil with two ends that is wound along a longitudinal axis of a ferromagnetic core, a magnet, and a suspending device that its first end is designed to be fixed to the body and its second end is designed to be fixed to the magnet. The first end of the core is design to be at close proximity to the magnet and the longitudinal axis of the core is designed to be substantially aligned vertically to the magnetic axis of the magnet. The vibrations of the body can cause a relative alternating movement between the core and the magnet that can create alternating voltage between the ends of the coil.
