Disclosed are devices and methods useful for confined-channel digital microfluidics that combine high-throughput droplet generators with digital microfluidic for droplet manipulation. The present disclosure also provides an off-chip sensing system for droplet tracking.

Method and device for tracking and manipulation of droplets

The present disclosure relates to digital microfluidic systems having an electrode bus controlled by a single actuation input, and methods for droplet manipulation using the electrode bus. Particularly, aspects are directed to a digital microfluidic system including a first group of droplet actuation electrodes formed in a substrate, a first wiring bus formed in the substrate and connected to each electrode in the first group of droplet actuation electrodes, and a first single point of actuation connected to the first wiring bus; and a second group of droplet actuation electrodes formed in the substrate, a second wiring bus formed in the substrate and connected to each electrode in the second group of droplet actuation electrodes, and a second single point of actuation connected to the second wiring bus.

Digital microfluidic systems with electrode bus and methods for droplet manipulation

The present disclosure relates to digital microfluidic systems. Particularly, aspects are directed to a digital microfluidic system that includes a droplet chip having a substrate, a plurality of electrodes and corresponding plurality of conducting vias or embedded conductive posts formed in the substrate, and a dielectric layer formed over the plurality of electrodes; and a control chip having a substrate, a plurality of transistors and corresponding wiring layers formed in the substrate, and a plurality of contacts formed over the plurality of transistors. Each of the plurality of contacts is electrically connected to a corresponding transistor of the plurality of transistors, and one or more of the plurality of contacts is removably connected to one or more of the plurality of conducting vias or embedded conductive posts such that one or more of the plurality of transistors are electrically connected to one or more of the plurality of electrodes.
