Presentation: P03018

In the past few years a tremendous effort has been invested in application technologies to master miniaturized fluidic handling in the field of nano dispensing and lab-on-a-chip applications. One of the technical challenges is how to control and switch fluids on a chip level whereby robustness, reliability and manufacturing cost are the key elements.

Applying hot film anemometer technology for a flow control sensor and a micro valve based on a piezoelectric bending actor, whose volume displacement is transferred by a hydraulic system to the closure membrane of a valve, proved to be a very suitable solution to master the above mentioned criteria. Such a concept provides switching facilities with a high open/close ratio for biochemical reagents or components between dispenser tips, reservoirs or reaction vessels.

The poster will present design, realization and experimental data of a low cost fluidic flow control sensor and the piezoceramic driven micro valve.
