Abstract: A microfluidic mixing device comprises a main channel and a number of secondary channels extending from a portion of the main channel and entering another portion of the main channel. A number of actuators are located in the secondary channels to pump fluids through the secondary channels. A microfluidic mixing system comprises a microfluidic mixing device. The microfluidic mixing device comprises a main fluid mixing channel, a number of main channel actuators to pump fluid through the main fluid mixing channel, a number of secondary channels fluidly coupled to the main fluid mixing channel, and a number of secondary channel actuators to pump fluids through the secondary channels. The microfluidic mixing device also comprises a fluid source, and a control device to provide fluids from the fluid source to the microfluidic mixing device and activate the main channel actuators and secondary channel actuators.

Abstract: A fluid ejection device including, at least, one recirculation system is disclosed. Such recirculation system contains, at least, one drop generator, recirculation channels that include an inlet channel, an outlet channel and a connection channel and a fluid feedhole that communicates with the drop generator via the inlet channel and the outlet channel of the recirculation channel. The recirculation channels can be asymmetrical with reference to the drop generator.
