The nowadays biomedical applications need manipulations of very small amount of liquids. The classical pumps with movable valves suffer from the fatigue of the movable parts, having a reduced lifetime and can destroy some biological macromolecules. A valveless micropump with a diffuser/nozzle element is in agreement with the silicon technology and bioliquids requirements. This work proposes a micropump with diffuser/nozzle channels dedicated to charged bioliquids. There are presented applications of this kind of integrated micropump like biosensor and drug delivery device. The simulation with CoventorWare has taken into account a piezoelectric actuation.
