Original Kurzfassung:
A highly parallelizable approach for the precise
dosing of homogenous liquids is presented. Droplets of the
dosing liquid rest on a superhydrophobic plate featuring a 3x3
array of holes, which evaporate with time and therefore reduce
in size. If the size of the droplets is small enough, they are able
to pass through the holes, which can be subsequently used for
further applications. Furthermore, microheaters are screen-
printed around the holes of the superhydrophobic plate, in
order to accelerate the evaporation process. Experimental data
regarding temperature distribution and the improvement due
to the addition of the microheaters to the setup is provided.
