Description

In this work we present a low cost and low tech method for the fabrication of microfluidic channels purely made out of PMMA featuring a diaphragm. The channel is created in three steps where first the PMMA substrate is engraved using a laser engraver, second the channel is filled with liquid gallium, and third, after the solidification of the gallium, an UVcurable PMMA topcoat seals the channel. The fabricated channel features a diaphragm with a screen printed strain gauge on top. This strain gauge is able to measure the deformation of the diaphragm thus capable of detecting flow velocities in the range from 10 to 300 μL/min.
