Abstract
A battery charger for portable electronic devices and a portable electronic device are disclosed. In one embodiment, a battery charger housing forms a portion of an outer device shell or a protective case cover. Capacitors are located within the battery charger housing that include opposing spaced plates having contact segments thereon. An output power increasing, electrically resistive fluid is held within and partially fills an enclosed chamber that is boundaried by the contact segments. In response to movement of the portable electronic device, induced relative motion between the output power increasing, electrically resistive fluid and contact segments varies the fluid-contact segment contact within the enclosed chamber, thereby inversely alternating the capacitance between the pair of capacitors and triboelectrically generating an electrical charge. An electronic circuit, which is coupled to the opposing spaced plates, is configured to transfer the electrical charge to a battery associated with the portable electronic device.
