AXIAL LOADING FOR MAGNETOSTRICTIVE POWER GENERATION

摘要

A device generates electrical energy from mechanical motion in a downhole environment. The device includes a magneto strictive element and an electrically conductive coil. The magneto strictive 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.
