Original Kurzfassung:
In the domain of microfluidic devices, a paradigm
shift from application-specific to fully-programmable solutions
takes place (a similar development from ASICS to FPGAs has
been observed in conventional circuitry). So-called Programmable
Microfluidic Devices (PMDs) provide a promising platform in this
regard. Here, fluids can be pushed into various reaction vessels
whose inflow and outflow is controlled by valves. The regular
structure in combination with the flexibility of defining various
flow paths through valves allows to realize a vast range of
biological or chemical applications by only changing the corresponding
valve-control sequence. However, determining a sound
valve-control constitutes a non-trivial task. Although first automatic
approaches for this problem have recently been proposed,
we show that they frequently yield impractical control sequences.
In this work, we address this issue by providing a precise definition
of the underlying design task. Afterwards, we present complementary
solutions (both exact as well as heuristic) and discuss
how they guarantee a sound valve-control. Experimental evaluations
demonstrate that the proposed solutions are capable of
automatically generating a sound valve-control for PMDs.
