Computational design of mixers and pumps for microfluidic systems

Microfluidic Technology - an overview | ScienceDirect Topics

Yet, all microfluidic systems are in need of pumps to power the fluidics processes and valves to control and automate fluidic handling [146]. The pumps and valves typically used for microfluidic systems are bulky and expensive and require high power to operate, which is far from ideal for wearable devices that should be compact and power efficient.

Microfluidics: A general overview of microfluidics - Elveflow

Microfluidics is both the science which studies the behaviour of fluids through micro-channels, and the technology of manufacturing microminiaturized devices containing chambers and tunnels through which fluids flow or are confined. Microfluidics deal with very small volumes of fluids, down to femtoliters (fL) which is a quadrillionth of a liter. Fluids behave very differently on the
