Constructing an electromagnetically actuated micro pump requires clarity on the intended application, such as whether it is for a tabletop fountain or a surgical implant. The definition of "micro" is crucial, as it influences the design and materials needed, particularly regarding pressure and flow requirements. For low-pressure applications, a design similar to an artificial heart with check valves and an oscillating membrane may suffice. Conversely, for high-pressure or specialized fluids, advanced technologies like nanotech or magnetohydrodynamics may be necessary. Companies like Lee Products offer relevant solutions, although they may be costly and not readily available off the shelf.
