Gach, Philip; Singh, Anup K.

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.
