Fundamentals and Application of Electrowetting on Dielectrics
A review of the electrowetting EW phenomenon and its applications is provided. The state
of the art includes already implemented technologies like EW displays or variable focus lenses but
also laboratory level researches in the lab-on-chip and fluid manipulation field. In the second part of
the work some preliminary experimental results are provided for the electrowetting on fluoropolymer
coated anodized aluminum, as example of EWOD electrowetting on dielectrics. Anodization was performed
in weakly acidic or neutral 2% wt. boric acid solution in water with an applied voltage range
between 10 and 40 V, then coating the surface with AF 1600. Experimental electrowetting data fit
with the Young-Lippmann relation, confirming aluminum as a promising material for electrowetting applications.
