Electrowetting Station

Electrowetting station consists of movable x-y stage, CCD camera and zoom lens (top and side view), nano-injector syringe and controller, DC power supply, and probes. This setup is to monitor the electrwetting action of liquid droplet on various hydrophobic surfaces like Teflon, Fluoropel, and Cytop. We can also observe the competitive electrowetting between water and oil by applying voltages. In addition, using this station, the electrical (I-V and C-V) and optical (transmission spectrum) characteristics of electrowetting devices such as electrowetting displays and liquid state field effect transistors (LiquiFETs) can be measured and analyzed using LabVIEW program.
