    Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator that is easily manufactured and less contaminated when various fluids are used.SOLUTION: A fluid pumping device (300) includes micro fluid devices (301-303) and piezoelectric actuators (311-313) externally coupled to the microfluidic devices. The piezoelectric actuator has an axial displacement along a lengthwise axis responsive to application of a bias voltage. The axial displacement of the piezoelectric actuator operates internal valves (346, 348) or an internal pump chamber (342) of the micro fluid device.

    Abstract: Fluidpumpvorrichtung (100, 200) enthaltend einen piezoelektrischen Aktor (110), welcher extern gekoppelt ist mit einer mikrofluidischen Vorrichtung (130, 230). Der piezoelektrische Aktor hat eine axiale Auslenkung entlang einer längsgerichteten Achse in Reaktion auf ein Anlegen einer Biasspannung. Die axiale Auslenkung des piezoelektrischen Aktors betreibt eines von einem internen Ventil (240, 245) und einer internen Pumpenkammer (140) der mikrofluidischen Vorrichtung.
