This section provides overview, applications, and principles of micropumps. Also, please take a look at the list of 12 micropump manufacturers and their company rankings.
A micropump is a small, precise pump that is used to control and manipulate insignificant amounts of liquid.
They are used in analytical instruments and in different fields of medicine, biotechnology, and nanotechnology.
Micropump can be classified into mechanical types, which require a mechanical power mechanism, and non-mechanical types, which are driven by physical external forces.
The most common type of micropump is the mechanical piezoelectric micropump. Non-mechanical types include light-driven micropump, micropump operated by nanomotors, and micropump that utilize capillary action.
Micropumps are used in precision instruments, medical devices, biotechnology, and nanotechnology.
The micropumps commonly sold are mechanically driven voltage micropumps, but depending on the application, it may be more effective to employ non-mechanically driven micropumps as well.
Examples of micropumps uses are shown below.
This section describes the principle of operating micropumps, from mechanical drive to non-mechanical light driven piezoelectric micropumps, micropumps operated by nanomotors, and micropumps that use capillary action.
Piezoelectric micropumps transport liquids by expanding or compressing a membrane called a diaphragm. Some products are equipped with valves for more precise liquid transport.
Light-driven micropumps transport liquids by utilizing the pressure radiation of light, a phenomenon in which a force acts on an object when light is reflected or refracted off the surface of the object. It is mainly used in the biotechnology field.
Nanomotor micropumps use nanomotors, which can convert intracellular energy into mechanical movement, to transport liquids.
Capillary micropumps use the capillary phenomenon, in which the fluid inside a thin tubular object rises due to surface tension, to transport the liquid.
