Abstract
An active microfluidic droplet generation device includes a droplet generation junction joining at least one continuous phase channel for carrying a ferrofluid, and a dispersed phase channel for carrying a dispersed phase (e.g., aqueous) flow. A miniature electropermanent magnet (EPM) upstream from the junction generates a magnetic field to modulate a flow rate of a ferrofluid in the continuous phase channel so that dispersed phase droplets are generated with volumes actively controlled on-demand and under continuous flow.
