Abstract
Digital microfluidic and analyte detection 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 and second substrates has an electrode array configured to generate electrical actuation forces to urge at least one droplet within the gap along the at least one of the first substrate and the second substrate. The electrode array has a plurality of electrodes defining an electrode array area in plan view. At least one of the first substrate and the second substrate has a well array defining a well array area in plan view. The well array area is bounded within the electrode array area and overlapping a portion of each of the plurality of electrodes. The well array area overlaps less than 75% of the electrode array area in plan view.
