摘要: Electrochemical actuation is disclosed for fluid movement and flow control in microfluidic devices, allowing for miniaturization, minimal power requirements, single-use disposability and engineering of small, complex fluidic networks. In one embodiment, a single-dose fluid delivery device is operable to deliver a bolus dose, in a single extended stroke or in multiple repeated doses. The device uses three electrochemically-actuated chambers, two of the chambers operating as inlet/outlet valves for the device and a third providing both a temporary containment and pumping action. By sequential manipulation of the fluid pressure in the three chambers, fluids may be delivered in precise quantities by the device.

摘要: The invention provides electrochemically-based methods and devices for producing fluid flow and/or changes in fluid pressure. In the methods and devices of the invention, current is passed through a divided electrochemical cell. Adjacent compartments of the cell are divided by a separator which comprises an ionically conducting separator. Each compartment includes an electrode and an electrolyte solution or ionic liquid. The electrolyte solution(s) or ionic liquid(s) and the ionically conducting separator are selected to obtain the desired relationship between the current through the cell and the fluid flowrate and/or change in fluid pressure.
