Abstract: A digital microfluidic device includes an array of controllable electrode pads alignable with a fluid passageway and a control portion. The control portion is to cause electrowetting movement of a droplet within the fluid passageway through a circuit of multiple different zones of the electrode pads. The electrowetting movement is to iteratively expose the droplet within a current zone of the different zones for a selectable current time period at a current temperature of a list of consecutive temperatures, further expose the droplet within the current zone, for each respective selectable subsequent time period, at each respective subsequent temperature of the list which is greater than the current temperature, and move the droplet into a subsequent zone of the different zones when one of the respective subsequent temperatures is less than the current temperature.
