Abstract
A downhole electrical power generation device is provided that includes at least one magnetic element, an electrically conductive element, and a member configured to be positioned within downhole fluid and to vibrate when the downhole fluid flows across a surface of the member. One of the magnetic element and the electrically conductive element is positioned on the member, and the other is configured to be positioned such that the electrically conductive element is located in a magnetic field produced by the at least one magnetic element to generate electrical power on vibration of the member. A method of generating electrical power downhole is further provided.
