Electrowetting is now used in a wide range of applications from modular to adjustable lenses, electronic displays (e-paper), electronic outdoor displays and switches for optical fibers. Electrowetting has recently been evoked for manipulating soft matter particularly, suppressing coffee stain effect. … See more Electrowetting is the modification of the wetting properties of a surface (which is typically hydrophobic) with an applied electric field. See more The electrowetting of mercury and other liquids on variably charged surfaces was probably first explained by Gabriel Lippmann in 1875 and was certainly observed much earlier. See more Reverse electrowetting can be used to harvest energy via a mechanical-to-electrical engineering scheme. See more Optoelectrowetting, and photoelectrowetting are both optically-induced electrowetting effects. Optoelectrowetting involves the use of a photoconductor whereas photoelectrowetting use a photocapacitance and … See more The electrowetting effect has been defined as "the change in solid-electrolyte contact angle due to an applied potential difference between the solid and the electrolyte". The phenomenon of … See more Another electrowetting configuration is electrowetting on liquid-infused film.
