Design and experimental investigation of a bi-directional valveless electromagnetic micro-pump

The Finite Volume Method an Alternative Method for LF Electromagnetic Problems

“…In addition, the magnets are placed in opposite polarities. For more details on this micro-actuator as dimensions we refer to [22,23]. The actuating mode consists with moving vertically both permanent magnets inside a non-magnetic cylindrical channel.…”

Flow rate-controlled pipetting for microfluidics: second-generation flexible hydraulic reservoir (FHRv2)

“…The common desired characteristics of these pumping systems include (i) flow control, (ii) a wide range of flow rates, (iii) an appropriate back pressure and ideally (iv) low-cost. Some micro pumps employ moving mechanical parts, typically an oscillating diaphragm actuated by a number of mechanisms, including hand power [10,11], electrostatic [12], electromagnetic [13][14][15][16], piezoelectric [17][18][19], thermo-pneumatic [20] forces or rotary motion of vanes and gears [21]. Even though diaphragms made of soft material are utilized most of the time, [12][13][14][15][16][17][18][19]22], thermoplastic elastomers were also implemented, which enabled production of the device by common mass production techniques [23,24].…”

Conception of a New Generation of 3d Biomimetic Microvalves for Medical Application

“…In addition, a micropump plays an important role in targeting transport of tracing substances (Laser et al 2004, Woias et al 2005. It can carry small and precise volume of liquids for chemical, biological or medical systems (Amrani et al 2018). Micropumps are appropriate tools for drug delivery in the body, suitable for modern biotechnology drug, provideing high precision delivery (Cui et al 2006, McAllister et al 2000.…”
