Claim Text:
1. A droplet actuator comprising: a. a top substrate and a bottom substrate separated to form a droplet operations gap, wherein the droplet operations gap is filled with a filler fluid; b. a sidewall and an opposite sidewall bounding the droplet operations gap, thereby creating a droplet operations channel; c. an arrangement of droplet operations electrodes on the sidewall; and d. an arrangement of one or more ground electrodes along the opposite sidewall, wherein the one or more ground electrodes are connected to an electrical ground; wherein multiple droplet operations may be conducted on one or more droplets in the droplet operations gap while maintaining substantially consistent contact between the one or more droplets and the one or more ground electrodes, thereby permitting completion of the multiple droplet operations without interruption by bubble formation in the filler fluid in the droplet operations gap.
