ELECTRICALLY CONTROLLED FLUID DISPLACEMENT DEVICE

摘要

The invention relates to devices by means of which it is possible to cause fluid globules to circulate within a capillary space by means of pairs of electrodes establishing capture sites. The invention provides a device in which the electrodes of two successive pairs have in common at least one indentation comprising a convex part and a concave part. The invention is applicable, in particular, to the visual display and storage of electrical data by means of movable indices in the form of globules.
