Abstract:
1. A liquid moving apparatus comprising: a container having a holding chamber enclosed by first and second end walls facing against each other and side walls connecting the first and second end walls; a polarized or conductive first liquid filled in the holding chamber; a second liquid filled in the holding chamber and prevented from mixing with the first liquid; first and second electrodes for applying an electric field to the first liquid; and voltage application means for applying voltage between the first electrode and the second electrode, wherein the first and second electrodes are placed along a virtual axis extending in the direction where the first and second end walls face against each other, which is the direction orthogonal to the direction of the thickness of the container; the change of the position subject to the voltage application by the voltage application means to the direction of the extension of the first and second electrodes brings the first liquid contact with both of the first and second end walls and moves the entire first liquid surrounded by the second liquid along the virtual axis; and the second electrode is provided on the internal surface of the first end wall and the internal surface of the second end wall, which face the holding chamber, and includes multiple second electrode bodies in the direction of the extension of the virtual axis.
