Fluid transporting device using conductive polymer

A fluid transporting device, which uses a conductive polymer, and sucks and discharges a fluid, comprising:

• a pump chamber in which the fluid is filled;
• a casing unit that has the pump chamber formed therein, the casing unit having a movable wall portion, the movable wall portion defining an exterior surface of the casing unit;
• a diaphragm, supported inside the casing unit, one portion or an entire portion of which is formed by a conductive polymer film that is subjected to electrochemomechanical expansion and contraction, and which forms the pump chamber together with the casing unit;
• an opening portion that is formed on the casing unit, and used for carrying out discharging and sucking operations of the fluid in the pump chamber;
• an electrolyte chamber that is surrounded by the casing unit and the diaphragm and the movable wall portion, and which contains an electrolyte therein, with one portion of the electrolyte being in contact with the diaphragm;
• a power supply that applies a voltage to the conductive polymer film;
• a wiring portion that electrically connects the conductive polymer film to the power supply;
• and
• a pressure maintaining unit that maintains a pressure to be applied to the diaphragm within a predetermined range, by moving the movable wall portion.
