An energy generation apparatus includes a first element including at least one first magnet and a second element including at least one second magnet. The second element is movable with respect to the first element. The at least one first magnet and the at least one second magnet are oriented such that common poles of the at least one first and second magnets are temporarily in proximity to each other such that a repulsive magnetic force between the at least one first magnet and at least one second magnet causes relative motion between the first and second elements. Preferred embodiments of the apparatus include at least one positioning element or cam including an undulating or wave-like surface to control a position and/or an orientation of the at least one first magnet and/or the at least one second magnet.

Wireless power transmission (WPT) systems are provided. For example, the WPT system can use one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor. Embodiments utilize magnetic coupling and electromechanical resonance for safe, spatially distributed, low-frequency power delivery to portable devices.
