    摘要： A device generates electrical energy from mechanical motion in a downhole environment. The device includes a magnetostrictive element and an electrically conductive coil. The magnetostrictive element has a first end and a second end. The first and second ends are coupled between a rotor and a bearing. The magnetostrictive element is configured to experience axial strain in response to radial movement of at least one of the rotor or the bearing with reference to the other. The electrically conductive coil is disposed in proximity to the magnetostrictive element. The coil is configured to generate an electrical current in response to a change in flux density of the magnetostrictive element.

    摘要： A device generates electrical energy from mechanical motion in a downhole environment. The device includes a magnetostrictive element and an electrically conductive coil. The magnetostrictive element has a first end and a second end. The first and second ends are coupled between two connectors. The magnetostrictive element is configured to experience axial strain in response to radial movement of at least one of the connectors relative to the other connector. The electrically conductive coil is disposed in proximity to the magnetostrictive element. The coil is configured to generate an electrical current in response to a change in flux density of the magnetostrictive element.

    摘要： A device for generating electrical energy from mechanical motion includes a buoy housing and at least one force modifier disposed at least partially within the interior of the buoy housing. The force modifier receives an input force and applies a modified force to another component. The force modifier includes a hydraulic system and the hydraulic system includes a first hydraulic piston having a first area and a second hydraulic piston having a second area, where the first area and the second area are not equal.

    摘要： A device generates electrical energy from mechanical motion in a downhole environment. The device converts rotary motion into a linear strain in a magnetostrictive material. The device includes a rotor, a magnetostrictive element, and an electrically conductive coil. The rotor rotates within a stator of a drill string. The magnetostrictive element is attached to the rotor by a first ball joint. The magnetostrictive element is configured to experience axial strain in response to rotational movement of the rotor. The magnetostrictive element includes a second ball joint on an end of the magnetostrictive element opposite the first ball joint. The electrically conductive coil is disposed in proximity to the magnetostrictive element. The electrically conductive coil is configured to generate an electrical current in response to a change in flux density of the magnetostrictive element.
