Visual indicator and fluid dispenser

A device for fluid display comprising a reservoir, the reservoir defining an interior space delimited by an internal surface, the interior space comprising a polar, non-gaseous fluid, the internal surface of the interior space being phobic to the fluid, wherein the fluid is displaced without changing the polarity of the fluid but rather by changing the non-wetting behavior of the fluid and the internal surface of the interior space located between one of a plurality of control electrodes and a common electrode into a wetting behavior, the device filled with at least two immiscible fluids whereas one fluid is located within an area of an electrical field capable of being generated by the common electrode and a first control electrode and partially within the electrical field capable of being generated by the same common electrode and at least one further adjacent control electrode so that the sequential electric activation of control electrodes generates a deformation or movement of the fluid in the direction of the sequentially activated electric fields of the control electrodes, the device being arranged so that the position of the fluid relative to the control electrodes is detectable by one or a plurality of sensing electrodes, wherein at least one control electrode is transparent, wherein the fluids move along an indicia to indicate a measured value and wherein the indicia are placed below the electrodes.
