Bachelorthesis on the Characterization of Microfluidic MEMS-Devices (IPMS-2018-129)
Flow-regulation and -generation on a micrometer length scale are of high scientific and industrial interest in the ongoing trend of system miniaturization. The Fraunhofer IPMS thereby uses a patented class of lateral electrostatic bending actuators to develop a set of silicon based Micropumps and Microvalves devices. With the first prototype devices being released from the in-house cleanroom, the experimental determination of performance parameters of these devices presents the aim of this work. The starting point is the familiarization of working with a microfluidic characterization bench. With liquid volumes in the Nano-Liter range other measurement techniques may be required besides the usage of a standard flowmeter.
The determination of actuation-mode and frequency dependent flow-rate curves
Characterization of the generated differential pressure generated by the micropumps
Determination of the maximum flowrate curve under the influence of an imposed backpressure
Electrical Standard Characterization of chip-devices
Determination of the thermodynamic efficiency
Comparison of measured with analytical models and existing simulation data.
