The invention provides nonlimiting examples of structures for and methods of dispensing droplets in a droplet actuator. The droplet actuator structures and methods of the invention exhibit numerous advantages over droplet ac-tuators of the prior art. In various embodiments, the structures and methods of the invention provide, among other things, improved efficiency, throughput, scalability, and/or droplet uniformity, as compared with existing droplet actuators. Fur-ther, in some embodiments, the droplet actuators provide con-figurations for improved methods of loading and/or unloading fluid and/or droplets. In yet other embodiments, the droplet actuators provide fluid loading configurations for loading nu-merous fluid reservoirs in a substantially simultaneous and/or substantially sequential manner.

L'invention fournit des exemples non limitatifs de structures et de procédés destinés à distribuer des gouttelettes dans un actionneur de gouttelettes. Les structures de l'actionneur de gouttelettes et les procédés de l'invention présentent de nombreux avantages par rapport aux actionneurs de gouttelettes de l'art antérieur. Dans divers modes de réalisation, les structures et procédés de l'invention offrent, entre autres, de meilleurs résultats en termes d'efficacité, de débit, d'extensibilité, et/ou d'uniformité des gouttelettes, en comparaison des actionneurs de gouttelettes existants. En outre, dans certains modes de réalisation, les actionneurs de gouttelettes offrent des configurations pour des procédés améliorés de chargement et/ou déchargement de fluide et/ou de gouttelettes. Dans encore d'autres modes de réalisation, les actionneurs de gouttelettes offrent des configurations de chargement de fluide permettant de charger de nombreux réservoirs de fluide d'une sensiblement simultanée et/ou sensiblement séquentielle.
