Journal ArticleDOI
Breath Figures under Electrowetting: Electrically Controlled Evolution of Drop Condensation Patterns.
TL;DR: It is shown that electrowetting with structured electrodes significantly modifies the distribution of drops condensing onto flat hydrophobic surfaces by aligning the drops and by enhancing coalescence, and that the resulting reduced surface coverage under EW enhances the net heat transfer.
Journal ArticleDOI
On the shape of a droplet in a wedge: new insight from electrowetting
TL;DR: This work investigates the equilibrium shape and position of liquid drops confined in the wedge between two solid surfaces at an angle α and shows how the geometric constraint and electrowetting can be used to position droplets inside a wedge in a controlled way, without mechanical actuation.
Journal ArticleDOI
Controlling shedding characteristics of condensate drops using electrowetting
TL;DR: In this article, an ac electrowetting (ac-EW) with structured electrodes can be used to control the gravity-driven shedding of drops condensing onto flat hydrophobic surfaces.
Journal ArticleDOI
Contact angle hysteresis and oil film lubrication in electrowetting with two immiscible liquids
TL;DR: In this article, the authors demonstrate that CAH for electrowetting of water drops in ambient oil increases with increasing AC and DC voltage, taking into account the disjoining pressure of the fluoropolymer-oil-water system, short range chemical interactions, viscous oil entrainment, and electrostatic stresses.
Journal ArticleDOI
Slippery when wet: mobility regimes of confined drops in electrowetting
TL;DR: The results shed light on the complex dynamics of droplets in non-uniform channels driven by electric actuation, and can thus help the rational design of devices based on electrowetting-driven droplet transport.
