Abstract:
1. A microfluidic device for use in a continuous ink jet printer comprising at least one first channel for feeding a first fluid, at least one second channel for feeding a second fluid, and a nozzle, the channels intersecting such that shear forces allow a jet of the first fluid to form within the second fluid and to subsequently disintegrate to form spaced droplets of the first fluid contained within the second fluid prior to reaching the nozzle so that a composite jet of droplets of the first fluid and the second fluid is ejected through the nozzle, the microfluidic device further comprising means for perturbing the flow of the composite jet positioned proximate to the nozzle from which the composite jet flows, and means to individually perturb the path of each droplet of said first fluid within said second fluid.
