Original Kurzfassung:
This work presents a method for integrating screen
printed transducers into microfluidic chips fabricated
from polymers. Screen printed structures are thin
enough not to disturb the flow while being cost
efficient in fabrication. In contrast to previously
presented methods [1] for the integration of screen
printed sensors, this fabrication technique prevents
leakages originating in the gluing of several different
materials, e.g. glass, paper and polymers. As an
example, a thermal flow velocity sensor embedded
into a microchannel made from poly(methyl
methacrylate) (PMMA) is presented.
