A magnetic momentum transfer generator utilizes three or more magnets aligned with each other. A first control magnet is positioned outside a coil. A second magnet is positioned within the windings of the coil and a third magnet is positioned on the opposite side of the coil opposite the control magnet. When the control magnet rotated or moved, mutual magnetic flux lines generated by all three magnets and passing through the coil winding are aligned at right angles to the coil, thereby inducing a maximum voltage at the terminals. This generator is particularly useful for short burst radio micro-transmitters that can be used for battery-less and wireless switching applications.

A transducer assembly configured to convert a pyrotechnic initiation to an electrical signal may comprise a magnet, a hollow tube, and a conductive element. The hollow tube may be wrapped around the magnet in the shape of a coil. The hollow tube may be at least partially filled with a thermite. The conductive element may be coupled to an outlet of the hollow tube. The conductive element may seal the outlet of the hollow tube.

A solid-state electromagnetic rotor, including a plurality of salient pole pieces arranged around a supporting structure, wherein a first end of each salient pole piece is attached to the support structure and a second end of each salient pole piece points outward away from the supporting structure. The wires wound around each salient pole piece, wherein when the wires of the plurality of salient pole pieces are sequentially excited by an excitation circuit. The salient pole pieces are energized to provide a moving polar magnetic field in the form of distinct magnetic poles as desired to accomplish power generation.

A first and a second type of apparatus for production of electrical energy are described, as well as a first and second type of methods for the production of electrical energy.

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.
