Abstract
In an embodiment, a fluid ejection device includes a fluidic channel having first and second ends and a drop generator disposed within the channel. A fluid reservoir is in fluid communication with the first and second ends of the channel, and an alternating-current electro-osmotic (ACEO) pump is disposed within the channel to generate net fluid flow from the reservoir at the first end, through the channel, and back to the reservoir at the second end.
