Characterisation of medical microfluidic systems regarding fast changing flow rates using optical front tracking methods

In medical applications of liquid flows, fast changing flow rates are common. Flow adjustments during infusion therapy lead to significant flow deviations. In complex flow systems, flow rates and concentrations of drugs are often different from expected values [1 –4]. To control microfluidic devices or intelligent systems, suitable actuators [5] and corresponding sensors are required. To investigate and furthermore control complex flow systems, a measuring technique to characterise the dynamic limitations of conventional flow meters is required.
