A Variational Approach to Contact Angle Saturation and Contact Line Instability in Static Electrowetting [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2009 Drops of a conducting fluid in electrowetting devices tend to spread when a difference of potential V o is set between the drop and an electrode external to it. The classical Lippmann theory predicts unlimited spreading, with a decrease of the contact angle between drop and solid substrate, as one increases V 0 .

Observation of contact angle hysteresis due to inhomogeneous electric fields
Communications Physics, 2021 Wetting of surfaces can be affected by surface roughness, presence of surface chemical defects, or by electric fields. Here, the authors perform electrowetting experiments on microstriped electrodes and show that the droplet’s static contact angle ...
