“…Micromixer driven by electrothermal effect also involves lots of multi-physics phenomena which could be used in micromixers [ 59 , 60 , 62 ]. Recently, Kunti et al [ 63 ] proposed an alternating current electrothermal micromixer consisted of eight pairs of asymmetric electrodes with AC voltage.…”

Microfluidic devices have attracted increasing attention in the fields of biomedical diagnostics, food safety control, environmental protection, and animal epidemic prevention. Micromixing has a considerable impact on the efficiency and sensitivity of microfluidic devices. This work reviews recent advances on the passive and active micromixers for the development of various microfluidic chips. Recently reported active micromixers driven by pressure fields, electrical fields, sound fields, magnetic fields, and thermal fields, etc. and passive micromixers, which owned two-dimensional obstacles, unbalanced collisions, spiral and convergence-divergence structures or three-dimensional lamination and spiral structures, were summarized and discussed. The future trends for micromixers to combine with 3D printing and paper channel were brought forth as well.

“…Act micromixers, require external energy sources, are preferred over passive microxers due to their capacity to mix rapi in confined volumes of liquids in the absence of flow, and thus have a smaller footprint. To date, many different typ of active micromixers have been developed, utilizing a variety of external sources such as pressure 16,17 , acoust 18,19 , magnetic fields 20,21 , electric fields 22,23 , thermal fields 24,25 , etc. Reviews of active micromixer can be found 15,26,27 .…”

For many blood-based diagnostic tests, including prophylactic drug analysis and malaria assays, red blood cells must be lysed effectively prior to their use in an analytical workflow. We report on a finger-actuated blood lysate preparation device, which utilises a previously reported acoustofluidic micromixer module. The integrated device includes a range of innovations from a sample interface, to the integration of blisters on a laser engraved surface and a large volume (130 μL) one-stroke manual pump which could be useful in other low-cost microfluidic-based point-of-care devices. The adaptability of the acoustic mixer is demonstrated on highly viscous fluids, including whole blood, with up to 65% percent volume fraction of red blood cells. Used in conjunction with a lysis buffer, the micromixer unit is also shown to lyse a finger-prick (20 μL) blood sample in 30 seconds and benchmarked across ten donor samples. Finally, we demonstrate the ease of use of the fully integrated device. Cheap, modular, but reliable, finger-actuated microfluidic functions could open up opportunities for the development of diagnostics with minimal resources

“…Active micromixers depend on different external energy sources to disturb the fluids, increase the contact area, or induce the chaotic advection, thus enhancing the mixing effect. Based on the types of external energy sources, the active micromixers can be further categorized as pressure field driven [7,[13][14][15][16], electrical field driven [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], sound field driven [6,[34][35][36][37][38][39][40][41][42][43], magnetic field driven [44][45][46][47][48][49][50][51][52][53][54][55][56][57], and thermal field driven [58][59][60][61][62][63], etc. (Table…”

“…When an AC signal at high frequency was applied to the micro-heater, the thermal bubbles could grow periodically and collapse rapidly, thus generating turbulent flow in the fluids and increased mixing efficiency. Micromixer driven by electrothermal effect also involves lots of multi-physics phenomena which could be used in micromixers [59,60,62]. Recently, Kunti et al [63] proposed an alternating current electrothermal micromixer consisted of eight pairs of asymmetric electrodes with AC voltage.…”
