A new concept and devices for autonomous switching of valves and pumps in microfabricated flow channels are proposed. An electrowetting-based valve consisting of gold and zinc opened when an electrolyte solution reached the zinc part in a controlling flow channel and a mixed potential was applied to the gold valve electrode. Clock circuits that open the valves at predetermined times and logic circuits...
A new concept and devices for autonomous switching of valves and pumps in microfabricated flow channels are proposed. An electrowetting-based valve formed with a gold electrode was opened when an electrolyte solution reached a zinc electrode in a controlling flow channel. Following this, a H2O2 solution was introduced into a diaphragm micropump with manganese dioxide (MnO2) powder. Oxygen bubbles...
