摘要： An apparatus for harvesting energy is described. The apparatus includes a vibration component and a moving mass. The vibration component has a first and second end and further includes a magnetostrictive material. The vibration component further includes a conduction coil wrapped around the magnetostrictive material. The moving mass is coupled to the second end of the vibration assembly. The mass is configured to move in an oscillating path in response to forces acting on the vibration energy harvesting apparatus, inducing strain on the magnetostrictive material. The strain on the magnetostrictive material changes a magnetic property of the magnetostrictive material, inducing electrical energy in the conduction coil wrapped around the magnetostrictive material. Other embodiments of the apparatus are also described.

摘要： Embodiments described herein relate to a method and device for harvesting energy from a fluid flow by converting the kinetic energy of the flow into vibrational energy, which then may be converted to electrical energy by a magnetostrictive-based vibrational energy harvester. Some embodiments of this device rely on the principle of vortex-induced vibrations, where the frequency of the induced vibration is of the same order as the frequency of vortex shedding. Some embodiments of this device rely on the principle of turbulence- induced vibration, where the frequency of vibration can be significantly higher than the vortex shedding frequency, and is related to the turbulence frequency of the flow. Some embodiments also relate to converting energy from pressure pulses or differentials in the fluid. These embodiments in no way limit the vibration induction mechanism, and other principles of flow-induced vibration may be used in conjunction with the magnetostrictive-based vibrational energy harvester.

摘要： An apparatus harvests electrical power from mechanical energy. The apparatus includes first and second load-bearing structures, a plurality of magnetostrictive elements, and an electrical circuit or coil. The load-bearing structures experience a force from an external source. The magnetostrictive elements are arranged between the load-bearing structures. The load- bearing structures transfer at least a portion of the force to at least one of the magnetostrictive elements. In this way, at least one of the magnetostrictive elements experiences the force transferred from the load-bearing structures. The force on the magnetostrictive element causes a change in magnetic flux of the magnetostrictive element. The electrical circuit or coil is disposed within a vicinity of the magnetostrictive element which experiences the force. The electrical circuit or coil generates electric power in response to the change in the magnetic flux of the magnetostrictive element.

摘要： Apparatuses and associated methods for converting wave energy into electrical energy are disclosed herein. In some embodiments, a surface-based buoy can be connected to a magnetostrictive element that changes its output voltage when subjected to the in tension. To keep the heave plate under tension, a tether with a heave plate can be attached to the magnetostrictive element. Since the magnetostrictive element can be sensitive to zero tension (e.g., a slack in the tether) followed by a sudden increase in the tension, in at least some embodiments it is preferred to keep the magnetostrictive element tensioned at all times. In some embodiments of the present technology, an inertia-dominated heave plate may be designed to sink faster than the buoy falls in the trough of the wave, therefore keeping the tether tensioned at all times. For example, the design (e.g., mass, diameter, height) of the heave plate can be such that the static force of gravity S exceeds a sum of the drag D and inertia / under expected wave conditions.
