Abstract
Microfluidic technology is currently being applied to analytical systems but suitable valving elements are proving to be difficult to implement. We have recently developed a novel way to electrically regulate flow through microchannels via a structure that can be made using readily available microfabrication techniques. An electrical signal is used to stimulate silver deposition on a thin Ag-Ge-Se solid electrolyte layer in a small region of a channel. The electrodeposited silver, which is a high surface area fractal structure less than 1 μm in height and several hundred μm long, changes the fluid-surface interaction. In this paper we demonstrate that this effect can be used to regulate pressure-driven flow in a microchannel.
