Abstract
A micropump configured to control flow of an insulation fluid includes: a rectangular channel 370 configured to have a rectangular shape in which a movement passage of the insulation fluid; a planar electrode forming section 310 configured to be formed inside the rectangular channel and have a planar shape for applying an electric field; an inflow section 320 configured such that the insulation fluid flows in; and an outflow section 330 configured such that the insulation fluid flows out. Since an insulation fluid with low conductivity in a range of 10−10 to 10−12 S/m is transported with a simple technical structure without using a complicated component, it is possible to obtain the advantage of cost saving and application to various minute dynamics devices.

A micropump configured to control flow of an insulation fluid, the micro pump comprising:
- a rectangular channel (250) configured to have a rectangular shape in which a movement passage for the insulation fluid is formed;
- an electrode forming section (210) configured to be formed inside the rectangular channel and include a plurality of electrodes, the plurality of electrodes having a cylinder shape for applying an electric field;
- an inflow section (230) configured such that the insulation fluid flows in;
- and
- an outflow section (240) configured such that the insulation fluid flows out,
- wherein the movement passage is formed along a longitudinal direction of rectangular channel (250) between the inflow section (230) and the outflow section (240),
- wherein the electrode forming section (210) includes:
- a ground electrode connecting portion (211) configured for applying a ground voltage (GND);
- an external power supply connecting portion (212) configured for applying a direct-current (DC) or alternating-current (AC) voltage supplied from an external power supply;
- a first cylinder electrode upper joining portion (213) extended from the external power supply connecting portion (212) in the longitudinal direction;
- and
- a second cylinder electrode upper joining portion (214) and a third cylinder electrode upper joining portion (215) extended from the ground electrode connecting portion (211) in the longitudinal direction,
- wherein the plurality of electrodes are extended from the first cylinder electrode upper joining portion (213), the second cylinder electrode upper joining portion (214), and the third cylinder electrode upper joining portion (215) to have the cylinder shape, and
- wherein the first cylinder electrode upper joining portion (213) is disposed between the second cylinder electrode upper joining portion (214) and the third cylinder electrode upper joining portion (215).
