Abstract
A microfluidic pumping system configured to prevent backflow from an outlet of the system toward an inlet of the system. The microfluidic pumping system comprising a gear housing that has an inlet and an outlet and that houses a drive gear, an idler gear and a drive shaft. The system further includes a front end plate that is coupled to a first surface of the gear housing and a rear end plate that is coupled to a second, different surface of the gear housing. Also coupled to the gear housing is a first and second Halbach magnet arrays that is disposed between the front end plate and the rear end plate. The first and second Halbach magnet arrays include one or more solenoids and the first Halbach magnet array is disposed proximate to the drive gear and the second Halbach magnet array is disposed proximate to the idler gear.
