First Claim
Patent Images
1. A droplet actuator comprising a base substrate and a top substrate separated to form a gap, wherein:
- (a) the base substrate comprises electrodes configured for conducting droplet operations in the gap;
(b) the top substrate comprises a first substrate portion coupled to a second frame portion, where the second portion comprises one or more openings establishing a fluid path extending from an exterior of the droplet actuator and into the gap, wherein the first substrate portion and second frame portion are not made of the same material; and
(c) one or more openings formed in the second frame portion of the top substrate establishing a fluid path extending from an exterior of the droplet actuator and into the gap.
