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： Embodiments of an apparatus for harvesting electrical power from fluid motion are described. The apparatus includes a magnetostrictive component having an internal pre-stressed magnetostrictive core. A magnetic property of the magnetostrictive core is configured to change with changes in stress within the magnetostrictive core along at least one direction within the magnetostrictive component. Also, forces at least partially due to fluid motion results in changes of stress within the magnetostrictive core and consequently change the magnetic property. The magnetostrictive component is further configured such that the change in the magnetic property will result in a change in the magnetic flux, which can be used to generate electrical power.

摘要： A method and device for generating electricity from ocean waves. The device includes at least one magnetostrictive element and one or more electrically conductive coils or circuits. When the magnetostrictive element is deployed in a body of water, the motion of the body of water, including wave motion, causes changes in the strain of the magnetostrictive element. The electrically conductive coil or circuit is within the vicinity of the magnetostrictive element. A corresponding change in magnetic field around the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit.

摘要： A method and device for using magnetostriction to generate electricity from fluid motion. The device includes a first structural component, an outer housing, and a strain structure. The outer housing substantially circumscribes the first structural component and at least partially defines an annular space between the first structural component and the outer housing. The strain structure is coupled within the annular space between the first structural component and the outer housing. The strain structure experiences a change in physical strain imposed by a bearing in response to a relative movement between the bearing and the strain structure. The strain structure includes a magnetostrictive material to generate a magnetic field in response to the change in the physical strain.

摘要： A method and device for energy conversion from a moving fluid to electrical energy. The device includes at least one magnetic structure, at least one coil structure, a rotating component, and a rotary to linear motion conversion mechanism. The at least one coil structure includes electrically conductive material. The rotating component rotates relative to a corresponding axis of rotation in response to forces applied by the moving fluid on a structure coupled to the rotating component. The rotary to linear motion conversion mechanism is coupled to the rotating component. Rotation of the rotating component around the corresponding axis of rotation generates a relative linear displacement between the at least one magnetic structure and at least one coil in the at least one coil structure. The relative linear displacement between the at least one magnetic structure and the at least one coil generates electrical energy in the at least one coil structure.
