DEVICES AND METHODS FOR FLUID ACTUATION

Abstract:

Digital microfluidic device includes a first substrate and a second substrate aligned generally parallel to each other with a gap defined therebetween in side view. At least one of the first substrate and the second substrate include a first electrode array, a second electrode array spaced from and in electrical communication with the first electrode array, and a first interstitial area defined between the first electrode array and the second electrode array. At least one of the first electrode array and the second electrode array is configured to generate electrical actuation forces within an actuation area to urge at least one droplet within the gap along the at least one of the first substrate and the second substrate. At least one spacer is disposed in the first interstitial area to maintain the gap between the first substrate and the second substrate.
