Abstract
An electrowetting system for actuating droplets of a first composition and of a second composition. The system includes: a plurality of electrodes configured to manipulate droplets of fluid in a microfluidic space, each electrode being coupled to circuitry which applies driving voltages to the electrode; and a processing unit operably connected to a look up table correlating drive sequences to chemical species and at least one composition parameter. The processing unit is configured to: receive data of a first chemical species and a first composition parameter of the first composition; receive data of a second chemical species and a second composition parameter of the second composition; correlate a first drive sequence with the first chemical species and the first composition parameter; correlate a second drive sequence with the second chemical species and the second composition parameter; and output the first drive sequence and the second drive sequence to the electrodes.
