摘要： Embodiments of the subject invention pertain to a method and apparatus for vibrational energy harvesting via electromagnetic induction using a magnet array. Specific embodiments of the subject invention incorporate at least one conductive coil and at least one magnet array. Magnets used in such magnet arrays can be permanent magnets of various shapes, such as arc-shaped, square, rectangular, wedge, or trapezoidal. These magnet arrays can then be, for example, circular, hexagonal, rectangular, or square in external shape and create various types of internal magnetic fields, such as dipole, quadrupole, hexapole, or octapole magnetic fields. Through use of a magnet array, embodiments of the invention can increase the strength of magnetic fields by approximately 10 times compared to typical vibrational energy harvesters. The 10 time increase in the strength of the magnetic fields can result in up to a 100-fold increase in power. Preferably, the magnetic fields created by the subject device are substantially, if not completely, enclosed within the device.

摘要： Wireless power transmission (WPT) systems are provided. According to an embodiment, the WPT system uses 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.
