What is Microfluidics and Micro-pumps Industry ?
Microfluidics deals with the behavior, precise control and manipulation of fluids that are geometrically constrained to a small, typically sub-millimeter, scale. At this scale, fluid flows are characterized by very small Reynolds numbers which corresponds to laminar flow regimes. Microfluidic systems are used to handle extremely small fluid volumes down to less than picoliters. These systems usually incorporate micro-pumps to pump liquids and samples through microchannels and regulate pressures and flows precisely.
Types of Micro-pumps Industry
There are various technologies used to design and fabricate micropumps including mechanical, non-mechanical and electrochemical methods. Some common types are:
- Peristaltic micropumps employ the peristaltic motion of multiple fingers or membranes to transport fluids in microchannels. They are highly reliable but have complex mechanical structures.
- Electromagnetic micropumps use the Lorentz force induced by the interaction between a current and a magnetic field to pump fluids. They can achieve high flow rates but require bulky driving components.
- Piezoelectric Global micro-pumps utilize piezoelectric actuation to generate pressure or volume changes and transport liquids. They offer precise control and low power consumption but have low maximum pressures.
- Thermopneumatic micropumps make use of the expansion of gases upon heating to pump liquids. Though simple in design, their flows are temperature dependent and nonspecific.
Applications of Micro-pumps
Microfluidic systems integrated with micropumps have enabled a wide range of applications across various fields like biomedical devices, diagnostics, biomanufacturing, energy systems and more. Here are some key applications of micro-pumps:
- Lab-on-a-chip (LOC) and micro total analysis systems (μTAS): Micropumps facilitate automated chemical and biological analysis on microchips to enable portable point-of-care diagnostics and miniaturized testing platforms.
- Drug delivery: Implantable micropumps are used for controlled delivery of drugs, vaccines, insulin etc in the body at programmable rates over extended periods of time.
- Medical microfluidics: Microfluidic networks along with integrated micropumps find use in lab reagents handling, chemical synthesis, cell culture and tissue engineering applications in healthcare.
- Micro Reaction and separation systems: Micropumps power continuous microfluidic processes for chemical synthesis, catalytic reactions as well as fluid mixing and separations on microscale.
- Micro Batteries and fuel cells: They enable fluid control and management of reactants and products in micro-scale batteries, proton exchange membrane fuel cells, and direct methanol fuel cells.
- Environmental monitoring: Micropumps integrated into portable microfluidic devices enable continuous sampling and analysis of chemical, biological and radiological contaminants in air and water for environmental monitoring.
