Abstract: The present invention provides an electrochemical fabrication platform for making structures, arrays of structures and functional devices having selected nanosized and/or microsized physical dimensions, shapes and spatial orientations. Methods, systems and system components of the present invention use an electrochemical stamping tool for generating patterns of relief and/or recessed features exhibiting excellent reproducibility, pattern fidelity and resolution on surfaces of solid state ionic conductors and in metal. Electrochemical stamping tools of the present invention are capable high throughput patterning of large substrate areas and, thus, enable a robust and commercially attractive manufacturing pathway to a range of functional systems and devices including nano- and micro-electromechanical systems, sensors, energy storage devices and integrated electronic circuits.
