MULTI-FLUID ELEMENTS DEVICE WITH CONTROLLABLE FLUID LEVEL BY MEANS OF MATRIX ADDRESSING

摘要

The invention concerns a device comprising fluid elements arranged in a matrix configuration, the level of fluid in each element being controllable by means of an electric force. The device is further provided with: first means for applying an electric force to a number of selected elements in one or more of the rows of fluid elements; second means for applying an electric force to a number of selected elements in one or more of the columns of fluid elements; such that the fluid level rises in the selected elements to which an electric force is applied by both the first means and the second means; and memory means for applying an electric force to the selected elements for retaining the risen level in the selected elements. The fluid elements comprise capillary tubes which are arranged such that the level of fluid is controllable while exercising a threshold like behavior.
