“…Micropumps can mainly be classified into mechanical and non-mechanical ones according to the presence or absence of a movable part. The former includes piezoelectric (1), electrostatic (2), and thermo pneumatic pumps (3), and the latter includes electrokinetic (4) and magnetohydrodynamic pumps (5). In addition to these, there have recently been reported a micropumps driven by chemical reaction.…”

An electrochemical pump consisting of poly(acrylic acid) incorporating Cu 2+ ion was developed. The pump discharges and charges liquid at the level of a few hundred of picoliter per second upon expansion and contraction of the gel induced by reduction and oxidation of the copper, respectively. The pump discharged ca. 5 µl of water at -1.3 V vs. Ag/AgCl for 3 h, whereas charged ca. 1.2 µl at +1.0 V for 3 h. At constant currents of -4.4 and +4.4 µA cm -2 , the volumes of water discharged and charged were found to be nearly proportional to the charge at ca. 0.10 cm 3 C -1 for both reduction and oxidation processes, except for an initial stage of the electrolysis. Further, upon repeated galvanostatic electrolyses, the same volume-charge slopes were obtained. These results indicate a reversibility and reproducibility of the pump.
