“…The larger area of the IPDP thin fi lm in the stacked-type-I micropump leads to a larger electromagnetic force as well as a larger power, and results in a fl ow rate higher than those of the stacked-type micropumps II, III, and IV. According to authors' previous results (24) and other researchers' works, (23,27,28) the maximum fl ow rate occurred at the resonant frequency of the micropump due to the maximum defl ection. As shown in Table 1, the larger area of the IPDP thin fi lm leads to a larger electromagnetic force that results in a higher fl ow rate due to a larger defl ection.…”

In this paper, an innovative composite poly-dimethylsiloxane (PDMS) micropump with an electromagnetic drive for biomedical applications that feature low cost and simple assembly is investigated. The developed PDMS micropump based on a reciprocation principle was driven by electromagnetic force that causes cavitation inside a chamber to make fl uid fl ow. A composite PDMS thin fi lm, an iron-particle-dispersed PDMS (IPDP) thin fi lm, is designed, fabricated and driven by electromagnetic force to actuate the micropump. In this work, there are two categories of micropumps including stacked and inlaid types, and each category has four types of micropumps with different geometrical combinations of IPDP and PDMS thin fi lms. The results show that inlaidtype micropumps all have higher fl ow rates than stacked-type micropumps, and for an inlaid-type-I micropump, the largest IPDP thin fi lm area results in its highest fl ow rate among the categories. The inlaid-type-I micropump has a maximum fl ow rate and a backpressure of 1.623 ml/min and 361.84 Pa, respectively, when applying 30 V between 6 and 7 Hz with a low power consumption of 33 mW. As a result of its higher fl ow rate and new IPDP thin-fi lm design, this kind of full PDMS micropump is appropriate for biomedical applications.

“…To establish a quantitative link between these parameters, the pumping rate was measured at various applied pneumatic pressures (10,20,30 and 40 psi) and frequencies (5-70 Hz). An observation in Figure 8a shows the liquid pumping rates correlate with pneumatic pressures.…”

This study presents a double-side diaphragm peristaltic pump for efficient medium transport without the unwanted backflow and the lagging effect of a diaphragm. A theoretical model was derived to predict the important parameter of the micropump, i.e., the motion of the valves at large deformations, for a variety of air pressures. Accordingly, we proposed an easy and robust design to fabricate a Polydimethylsiloxane (PDMS)-based micropump. The theoretical model agrees with a numerical model and experimental data for the deformations of the PDMS membrane. Furthermore, variations of the generated flow rate, including pneumatic frequencies, actuated air pressures, and operation modes were evaluated experimentally for the proposed micropumps. In future, the theoretical equation could provide the optimal parameters for the scientists working on the fabrication of the diaphragm peristaltic pump for applications of cell-culture.
