  • Patent number: 11375912
    Abstract: Energy harvesting devices and methods for converting the mechanical energy of a flowing ionic solution, such as rainwater or seawater, into electric energy are provided. The energy harvesting devices include an electric current generating device that includes a metal layer and an amphoteric metal oxide film disposed over a surface of the metal layer. By moving an electric double layer across the surface of the amphoteric metal oxide film, an electric current is generated in the metal layer.
    Type: Grant
