Microfluidic flow-focusing in ac electric fields.
We demonstrate the control of droplet sizes by an ac voltage applied across microelectrodes patterned around a flow-focusing junction. The electrodes do not come in contact with the fluids to avoid electrochemical effects. We found several regimes of droplet production in electric fields, controlled by the connection of the chip, the conductivity of the dispersed phase and the frequency of the ...
متن کاملNumerical Study of the Controlled Droplet Breakup by Electric Fields inside a Microfluidic Flow-focusing Device
Droplet-based microfluidics has received extensive research interests due to its superior control over the fluid flow. Conventional passive microfluidic flow-focusing devices confront difficulties in controlling droplet sizes in dripping regime especially when the dispersed phase has a large viscosity. External electric fields have been reported as an effective tool to manipulate droplet breaku...
متن کاملFlow Focusing in Microfluidic Devices
This paper presents numerical analysis of the hydrodynamic flow focusing in rectangular microchannels. The low Reynolds number pressure driven flow in symmetric system of crossed channels with three inlets and one outlet is investigated. The numerical model is used to elucidate the origin of broadening of the focused flow sheet observed experimentally close to the side walls of the outlet chann...

متن کاملParallelization of microfluidic flow-focusing devices.
Microfluidic flow-focusing devices offer excellent control over fluid flow, enabling formation of drops with a narrow size distribution. However, the throughput of microfluidic flow-focusing devices is limited and scale-up through operation of multiple drop makers in parallel often compromises the robustness of their operation. We demonstrate that parallelization is facilitated if the outer pha...
