<P>PROBLEM TO BE SOLVED: To solve the problems that a mechanical or hydrodynamic method has had a complicated and easily clogging channel structure, high manufacturing costs, and a large dead volume and that an electrical method has had a simple channel structure but does not operate with a liquid of the concentration of physiological saline, which is medicinally and biologically important in a conventionally used micropump and a conventionally used micromixer. <P>SOLUTION: An AC voltage is applied across a pair of electrodes of which an interelectrode gap is vertically set to generate the flow of a fluid in the direction reverse to gravitation along the interelectrode gap to solve the problems. Especially, micropumps 43 and 44 can be implemented by forming a microchannel 11 in a vertical direction along the interelectrode gap and a micromixer 41 by forming a microchannel 11 in a horizontal direction intersecting the interelectrode gap at right angles. <P>COPYRIGHT: (C)2008,JPO&INPIT |
