Droplet dynamics driven by electrowetting
Physical Review E, 2022Even though electrowetting-on-dielectric (EWOD) is a useful strategy in a wide array of biological and engineering processes with numerous droplet-manipulation applications, there is still a lack of complete theoretical interpretation on the dynamics of electrowetting.

Electrowetting and electrowetting-on-dielectric for microscale liquid handling
Sensors and Actuators A: Physical, 2002This paper deals with electrowetting (EW) and electrowetting-on-dielectric (EWOD) principles applied to microfluidic devices. EW and EWOD are principles that can control wettability of liquids on solid surfaces using electric potential. While EW is controlling wettability of a certain electrolyte on a metal electrode by varying electric energy across ...

Contact Angle Saturation in Electrowetting
The Journal of Physical Chemistry B, 2005Electrowetting is the phenomenon of contact angle decrease under the influence of an external voltage applied across the solid/liquid interface. Electrowetting offers an interesting possibility to enhance the wettability of hydrophobic materials without altering the chemical composition of the system and thus could be incorporated in various ...

Nonwoven electrowetting textiles
Applied Physics Letters, 2007Electrowetting of two nonwoven textile platforms is reported. Demonstrated nonwoven textiles include a polyethylene naphthalate film that was laser milled with ∼125μm pores, and pressed paper that was made using wood microfibers of 35–50μm diameter. Vacuum deposition provided an Al electrode on the polymer textile whereas layer-by-layer nanoassembly ...

Continuous electrowetting (CEW) and refractive index matching have been used as the physical basis of an optical switch for multimode fibers. This switch has low cross talk (∼−30 dB), fast response times (∼20 ms), low operating voltage (∼1 V), and low power consumption (∼1 μW).

Bistable electrowetting displays
SPIE Newsroom, 2011The electrowetting D³ technology ("Droplet-Driven-Displays") was invented by ADT. Those displays have features like bistability and highest reflectivity, which offer unique application options for real "No Power ("green") applications ranging from indicators to billboards.

Electrowetting Fresnel lenticular
2012 IEEE 25th International Conference on Micro Electro Mechanical Systems (MEMS), 2012We report on the development of a Fresnel lenticular lens achieved by high-speed linking and driving of separately controlled electrowetting microprisms. We also report on the development of electrode patterning for three-dimensional structures using no photolithography on a film substrate.

Continuous electrowetting via electrochemical diodes
Lab on a Chip, 2011We describe a novel method for droplet transport combining electrowetting on dielectric (EWOD) and the diode-like behavior of valve metals to achieve unique actuation performance. While traditional EWOD droplet transport requires switching of voltage between multiple electrodes, our method, which we term continuous rectified electrowetting, utilizes a ...
