Device and system for converting mechanical energy into electric energy

A device for converting mechanical energy into electric energy, comprising:

• a first magnet and a second magnet, wherein the first magnet is arranged apart from the second magnet at a predetermined distance and in a manner movable in a direction toward the second magnet, and wherein same poles of the first magnet and the second magnet face each other;
• a first coil having a first plurality of windings that defines a first inner space, wherein the first coil is configured and arranged to receive the first magnet in the first inner space during a movement in the direction toward the second magnet and to generate a corresponding first induction voltage;
• a second coil having a second plurality of windings that defines a second inner space, wherein the first coil has a first coil central axis at a center of the first coil and the second coil has a second coil central axis at a center of the second coil, wherein the first coil and the second coil are arranged such that the first coil central axis and the second coil central axis are perpendicular to each other, wherein the second coil is arranged at least partially around the second magnet and is configured to generate a second induction voltage when the first magnet moves toward the second magnet.
