Abstract
System for storing and dispensing liquid in a digital microfluidic chip includes a plurality of reservoir electrodes defining a reservoir having an outlet and a first end opposite the outlet, the reservoir configured to be in fluidic communication with at least one device electrode proximate the outlet, the at least one device electrode and at least one of the plurality of reservoir electrodes configured to generate electrical actuation forces to dispense at least one droplet from the reservoir through the outlet. The plurality of reservoir electrodes include a first reservoir electrode proximate the first end, a reservoir outlet electrode proximate the outlet, and at least one intermediate reservoir electrode disposed between the first electrode and the reservoir outlet electrode. The first reservoir electrode, the reservoir outlet electrode, and the at least one intermediate reservoir electrode each has an electrode surface area in plan view greater than or equal to an electrode surface area of each of the at least one device electrodes.
