We demonstrate a novel stepper micropump for ferrofluid driven microfluidic systems. The rotor is a ferrofluid plug that works as a piston pushing another liquid in a circular microchannel. The actuation concept is similar to that of a stepper motor, where the angular velocity can be precisely contr...
