Abstract
In embodiments of the present invention, an energy extractor includes a capacitor which experiences capacitance and voltage changes in response to movement of a capacitor plate or of a dielectric material. In one embodiment, a third plate is positioned between first and second plates to create two capacitors of varying capacitances. In another embodiment, one capacitor plate is attached by flexible arms which permit movement across another capacitor plate. The above capacitors can be used singularly or with one or more other capacitors and are rectified either individually or in a cascaded arrangement for supplying power to a rechargeable energy source. The above capacitors can be fabricated on a substrate along with supporting electronics such as diodes.
