Abstract:This thesis describes the development of a number of microfluidic handling techniques, including; (i) the detection of individual liquid droplets using electrical position sensors; (ii) the generation and control over the three major microfluidic segmented laminar flow regimes; (iii) the creation of discrete liquid quanta by entirely chip-driven techniques, including on-chip valves and pumps; (iv) the driving around of those resulting liquid quanta; and (v) the combining of multiple microfluidic peristaltic pumps into a multiplexed arrangement, allowing for many pumps to be controlled by a limited number of external pneumatic connections. These techniques were integrated to create an overall microfluidic droplet routing platform, capable of generating and directing individual liquid elements to arbitrary locations within a large microfluidic A I array, using completely chip-driven actuations. As a testbed application, the microfluidic capabilities developed here were utilized in conjunction with an electrohydrodynamic-jet printing process to generate a high resolution heterogeneous printhead.
