摘要
A method and apparatus for motional/vibrational energy harvesting are disclosed. Embodiments of the subject invention utilize the non-resonant chaotic behavior of a free-rolling magnet to generate power. In one embodiment, the magnet can be spherical, cylindrical, or elliptical. The magnet can roll about a linear, cylindrical, helical, or cage-like track. The changing magnetic flux due to the magnet rolling about the track induces current in surrounding coils. The coils can be provided around the track using a continuous winding placement, segmented winding placement, or fractional winding placement. Multiple coil phases are also possible. For embodiments utilizing multiple magnets, spacers can be used to maintain a separation between magnets.
