Interrogation of Droplet Configuration During Electrowetting via Impedance Sp…

Abstract—Several parameters associated with the configuration of a microliter aqueous droplet are determined by the electrical impedance measurements conducted during electrowetting. In each case, the wetted area of a dielectric-coated electrode is first determined from the impedance data, and the known dielectric thickness and permittivity. The wetted area data is then employed in a series …
