An EO pump-based new type of micro fluidic system

This paper proposes an EO pump based novel type of micro fluidic control system, which can control both the output pressure and the output flow velocity. This system consists of an EO pump, a flow sensor, a pressure sensor and a fuel cell. By changing the driving voltage, the material of pipe and the two kinds of liquid, we get different output pressure and output flow velocity data. We proposed the mechanism using one fuel cell to solve the problem of gases generated by the EO pump. The characteristic evaluations have been carried out. The maximum flow velocity in the oil is 6.34 ¿l/min at the driving voltage 7.02 V.
