This paper shows for the first time a flow switch which is controlled by the Coriolis force on a centrifugal Jab-on-a-disk" platform. The Coriolis switch consists of an inverse Y- structure with one common upstream channel and two symmetric outlets. Above a certain threshold frequency coo, the Coriolis force becomes dominant to direct nearly 100% of the flotv in one of the outlets which is selected by the direction of rotation. The threshold fre- quency has been measured to be 350 rad s-l for a channel width of 360 urn and a depth of 125 ym. The results are supported by extensive CFD simulations.
