Abstract: In an example implementation, a method of controlling a microfluidic valve includes activating a first inertial pump at a first frequency, and a second inertial pump at a second frequency to create a first fluid flow pattern within a microfluidic valve. The method also includes adjusting at least one of the first frequency and the second frequency to change the first fluid flow pattern to a second fluid flow pattern.

Abstract: A microfluidic valve comprises a first reservoir, a second reservoir, an inertial pump and a channel connecting the first reservoir to the second reservoir. The second reservoir is to receive fluid from the first reservoir through the channel under a pressure gradient. The inertial pump is within the channel proximate the second reservoir and distant the first reservoir.
