| dc.description.abstract | Multi-Mechanism Energy Harvesters (MMEHs) combining magnetostrictive and inductive mechanisms with a shape and size similar to an AA battery. Included are MMEHs with (a) an inductive mode: a cylindrical tube, a rod lengthwise within the tube, permanent magnets with opposing polarities at opposing ends of the tube, an annular oscillatory magnet in the tube and between the magnets and around the rod; and a primary coil around the tube and oscillatory magnet, such that relative movement between the magnet and coil induces electrical current in the coil; and (b) a magnetostrictive mode comprising: piezoelectric cymbal transducers on opposing ends of the tube and comprising a magnetostrictive material surrounded by a secondary coil, such that movement of the magnetostrictive material induces voltage in the secondary coil. During use, electrical energy can be harvested from the relative motion between the magnet and coil and from the magnetostrictive material. | en |
