ABSTRACT:
Device for displacing drops of liquid by electrowetting, and a method for isolating two areas delimited by at least one wall including a step for:placing by electrowetting, in an aperture of said wall, a substance capable of reacting to at least one external stimulus in order to pass from a liquid state to a gel or solid state, forming a closure member.
