Influence of the Ground Electrode on the Dynamics of Electrowetting

open access: yesMicromachines, 2023
The ability to manipulate a liquid meniscus using electrowetting has many applications. In any electrowetting design, at least two electrodes are required: one forms the field to change the contact angle and the other functions as a ground electrode.

Impulse Efficiency of Ground Electrodes [PDF]

open access: yesIEEE Transactions on Power Delivery, 2009
The lightning current waveform has a major influence on the dynamic performance of ground electrodes. While high lightning current intensity improves the dynamic grounding performance due to ionization of the soil, very fast fronted pulses might worsen the performance in case of inductive behavior.
