I. INTRODUCTION
The term electrowetting, in its broadest sense, refers to techniques
by which one can control the apparent wettability (characterized by
the contact angle) of liquids, by applying an external electric
potential.111
While it has numerous applications,1220
electrowet-
ting is known to be limited by the so-called contact angle saturation
