Abstract
Fluid element device including fluid elements arranged in a matrix configuration having rows and columns with the level of fluid in each fluid element being controllable by electric force. The fluid elements include capillary tubes having electrode segments electrically insulated from one another such that each segments is receivable of a different voltage. A first voltage delivery circuit applies voltage to selected fluid elements in one or more rows of fluid elements and a second voltage delivery circuit applies voltage to selected fluid elements in one or more columns of fluid elements. The fluid level rises in the selected fluid elements to which voltage is applied by both the first and second voltage delivery circuits. The capillary tubes are structured and arranged such that the level of fluid in the selected elements can be retained independent of the application of voltage by the first and second voltage delivery circuits.
