A device and method for harvesting, generating, storing, and delivering energy to a load, particularly for remote or inaccessible applications. The device preferably comprises one or more energy sources, at least one supercapacitor, at least one rechargeable battery, and a controller. The charging of the energy storage devices and the delivery of power to the load is preferably dynamically varied to maximize efficiency. A low power consumption charge pump circuit is preferably employed to collect power from low power energy sources while also enabling the delivery of higher voltage power to the load. The charging voltage is preferably programmable, enabling one device to be used for a wide range of specific applications.

System for energy harvesting and/or generation, storage, and delivery

An electric double layer capacitor (EDLC) in a coin or button cell configuration having low equivalent series resistance (ESR). The capacitor comprises mesh or other porous metal that is attached via conducting adhesive to one or both the current collectors. The mesh is embedded into the surface of the adjacent electrode, thereby reducing the interfacial resistance between the electrode and the current collector, thus reducing the ESR of the capacitor.

Capacitors with low equivalent series resistance

A microelectronic battery is formed from Zn/Air technology as a volumetric energy storage device from soft lithography techniques. The microelectric battery includes an anode and a cathode disposed in an electrolyte tank having a volume &#x3c;1 mmthat is filled with an electrolyte.

Volumetric micro batteries

A microelectronic supercapacitor is amenable to being fabricated using micro electromechanical systems (MEMS) techniques. By utilizing MEMS techniques, the supercapacitor in accordance with the present invention can be formed with volumes <1 mm . As such, such microelectronic supercapacitor is suitable for use in applications in which only a few millimeters are available for both a supercapacitor and an energy storage device, such as a battery.

Micro-supercapacitor

A method for simultaneously producing areas of paraelectric states and areas of ferroelectric states on a single thin film layer, thereby reducing the number of processing steps required to produce integrated chips containing both standard capacitors and non-volatile memory devices from the number of steps needed using the conventional approach. A device containing both ferroelectric capacitors and non-ferroelectric capacitors using a single thin film as the dielectric.
