| 内容記述 | AC electro-osmotic (ACEO) pumps play an important role in a wide diversity of microfiuidic applications. To produce high flow velocities, an effective breaking of symmetry is prerequisite. Here, we introduced a ratchet-structured electrode for achieving high flow velocities and developed a ratchet ACED pump containing both ratchet and plane electrodes. The performance of our new ACED pump is evaluated experimentally. At an ac voltage of 30 V at 10kHz, a maximum net flow velocity of 1.1 mm/s is measured along the inclined direction of the ratchet teeth. Furthermore, we also directly observed the flow fields due to the slip velocity of ACEO, which provide a physical insight on the ratchet-type ACED pumps. | |||||||||
