<p>The invention relates to the use of a fluid mixture for electrowetting in a device that is suitable for this. According to the invention, the fluid mixture consists of at least two components, namely an electrically inducible liquid and an electrically inert fluid. These two components form a bi- or multiphasic mixture. The electrically inducible liquid responds to a change of an electric field that surrounds it or completely or partly permeates it, in such way that it changes its surface tension so that its form is changed too, particularly if only parts of its surface are permeated by the electric field, or if the field strength is distributed not homogenously. According to a particularly preferred embodiment, the electrically inducible liquid consists of propylene carbonate. As a result of using this liquid, the temperature range, in which a device being based on the electrowetting effect may be operated, is expanded in such way, that application areas are made possible which so far have not been usable using conventional, particularly aqueous, liquids.</p> |
