Abstract

Electrical micro-fluidic multiplex system comprises a channel for a liquid stream, electrodes arranged along the channel, and a control unit having several outlets for control signals for the electrodes. The electrodes are divided into groups, in which each group is assigned to the outlet of the control unit. The electrodes of each group are galvanically joined together and connected to the outlet of the control unit. The control signals are impulse signals and the sequence of the impulses of the control signals on the different outlets is smaller than the relaxation time of the degradation of the electrical field in the liquid between two electrodes. Preferred Features: The electrodes of the individual groups are connected in rows and/or in parallel or partially in rows and/or in parallel. Micro-fluidic networks reconfigured on an electrical path can be implemented.
