Abstract:
1. A fluid transporting device using a conductive polymer, and capable of sucking and discharging a fluid, said fluid transporting device comprising: a pump chamber configured to be filled with the fluid; a casing unit having said pump chamber formed therein, and forming one portion of a wall surface of said pump chamber; a diaphragm, supported inside said casing unit, at least one portion of said diaphragm being formed by a conductive polymer film that is subjected to electrochemomechanical expansion and contraction, and said portion of said diaphragm forming said wall surface of said pump chamber together with said casing unit; a first opening configured and arranged to guide the fluid to said pump chamber and a second opening configured and arranged to discharge pressurized fluid from said pump chamber; an electrolyte chamber surrounded by said casing unit and said diaphragm, and containing an electrolyte therein, a portion of said diaphragm being configured and arranged to contact the electrolyte; a power supply configured to apply a voltage to said conductive polymer film; a wiring portion electrically connecting said conductive polymer film to said power supply; and a pressure maintaining unit having an elastic member located inside said electrolyte chamber and on one portion of the wall surface of said electrolyte chamber, and configured to maintain a pressure applied to the diaphragm within a predetermined range by generating a pressure change in the electrolyte by using said elastic member.
