WebElectrowetting is the key principle behind Varioptic Lenses technology. Electrowetting occurs when a drop of insulating liquid (e.g., oil drop) is deposited on a flat surface made of a conductive material covered with an insulating and hydrophobic layer, and then both the drop and surface are immersed in a conductive liquid (e.g., electrolyte). Web1 Mar 2016 · Our electrowetting lenses tune over 20 diopters and have been demonstrated at 588, 1550 and 3000 nm wavelengths. Additionally, we have demonstrated prism elements with a steering angle of 0.56° at 1550 nm.

WebElectrowetting-based optical devices provide an advantageous and versatile alternative to conventional adaptive optics [1]. In lieu of moving parts, they are liquid-based and compact and can be integrated in small-scale optical systems. 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. The liquid-infused film is achieved by locking a liquid lubricant in a porous membrane through the delicate control of wetting properties of the liquid and solid phases.
