Abstract
According to a first aspect, the invention relates to a device (10) for electrochemically releasing a composition and comprising: one working electrode (30) comprising an electroactive conjugated polymer (40) containing or doped with said composition, a counter electrode (50), and a reference electrode (60). The device (10) is characterized in that it comprises electrical means (95, 100; 320; 165, 180) connected to the working electrode (30) and to the counter electrode (50) for obtaining at said working electrode (30) at least one composition releasing sequence (65) with respect to said reference electrode (60), each composition releasing sequence (65) comprising: a first voltametric pulse (70), followed by a rest period (80) during which no current is able to flow through said working electrode (30), followed by a second voltametric pulse (90), followed by an intermediate period (160) during which no current is able to flow through said working electrode (30).
