Electromagnetic device for generating electrical current and methods thereof

Abstract

An energy harvesting device (EHD) and method including a hollow outer envelope (201) having an inner wall (200) with a first predetermined magnetic field distributed on an inner surface of the inner wall, at least one inner core (202), free to move in the hollow envelope (200) characterized by a second predetermined magnetic field distributed on an inner surface of the at least inner core, the inner core being characterized by one or more convex projections of magnetically active material, at least one conducting loop (203) disposed at locations selected from the group consisting of the outer envelope and the at least inner core, so as to be suffused with magnetic flux due to the magnetic field distributions of the at least one inner core and the at least one outer envelope and generating an alternating current due to movement of the inner core within the outer envelope and a rectifying circuit in electrical connection with the at least one conducting loop (203) rectifying the alternating current into a current having a DC component.
