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...
Conductive structures on flexible substrates are expected to be the foundation of the next generation of electronics, displays, and solar cells. This work presents a simplified fabrication process for definition of electrode structures on silicone polymer. Flexible gold thin film structures on polydimethyl siloxane (PDMS) were successfully realised. This process is conducive to large area fabrication...
The fabrication and characterization of a fully integrated capillary electrophoresis (CE)-based microfluidic device with integrated carbon sensing electrode is described in this study. A combination of microfabrication protocols were employed for fabricating the hybrid polydimethyl siloxane (PDMS)/glass microfluidic device including chemical wet etching, soft lithography, and micromolding techniques...
