Flexible electrowetting and electrowetting on flexible substrates
SPIE Proceedings, 2011Electrowetting (EW) technology is shown to be quite flexible in operation and able to operate on flexible substrates. Complementary ON/OFF characteristics of EW devices have been obtained through a plasma irradiation and annealing process. This enables the design of EW array operation in a reduced power mode.

Droplet Energy Harvesting Is Reverse Phenomenon of Electrowetting on Dielectric
Advanced Functional Materials, 2021Electric energy is generated when water droplets slide down electrodes coated with a hydrophobic dielectric layer. The principle of energy generation needs to be clarified for the optimization and scalable design of the energy‐harvesting system.

Droplet impact characteristics on hydrophobic surfaces with partial electrowetting effects
The Physics of FluidsDroplet impact on surfaces integrated with the electrowetting effect has been recently explored to control droplet spreading and recoiling behavior on hydrophobic surfaces. With the integration of electrowetting, the spreading of the impacting droplet on

Langmuir, 2021
In this paper, a millimeter-sized bubble in water pending on a substrate is manipulated by applying an alternating current (AC) electric field, known as electrowetting on dielectric. In this setup, standing waves on the bubble surface are observed.

Annals of the New York Academy of Sciences, 2006
Abstract: Numerical simulation of a zero‐leakage microvalve is investigated where a liquid droplet is used as a gate to regulate the flow in a T junction. The droplet gate is activated by changing its surface tension via an applied electric field.

Hydrodynamic Flows in Electrowetting
Langmuir, 2008In this work, we found experimentally that there exist fairly strong fluid flows in AC electrowetting, which can be utilized as a means to mix the fluids in EWOD-based micro-devices. We visualized the internal flow. There may exist two distinct flow-generation mechanisms; one is the droplet oscillation, and the other is the electrohydrodynamic flow ...

The dynamics of droplet detachment in reversed electrowetting (REW)
, 2021Droplet actuation by electrowetting (EW) has drawn significant interest due to the potential applications in micro- and nano-fluidics, and the droplet departure is crucial for separation of the drop phase from the solid surface.

Reconfigurable virtual electrowetting channels
Lab Chip, 2012Lab-on-a-chip systems rely on several microfluidic paradigms. The first uses a fixed layout of continuous microfluidic channels. Such lab-on-a-chip systems are almost always application specific and far from a true "laboratory." The second involves electrowetting droplet movement (digital microfluidics), and allows two-dimensional computer control of ...
