Control of an electrowetting element

A device arranged to limit fragmentation of a first fluid, the device comprising:

• an electrowetting element comprising:
• a first support plate comprising a first electrode;
• a second support plate;
• the first fluid;
• a second fluid immiscible with the first fluid, the first fluid and the second fluid located between the first support plate and the second support plate;
• and
• a second electrode in contact with the second fluid;
• a control apparatus comprising:
• at least one processor;
• at least one memory comprising computer program instructions,
• the at least one memory and the computer program instructions operable to, with the at least one processor, cause the control apparatus to:
• receive first data corresponding with a first voltage with a first magnitude;
• generate the first voltage with the first magnitude;
• apply the first voltage between the first electrode and the second electrode;
• receive second data corresponding with a second voltage with a second magnitude;
• determine that the first magnitude is smaller than the second magnitude by comparing the first data with the second data;
• and, responsive thereto:
• determine a third magnitude of a third voltage, the third magnitude larger than the first magnitude and smaller than the second magnitude;
• generate the third voltage with the third magnitude;
• and
• apply the third voltage with the third magnitude between the first electrode and the second electrode instead of the second voltage, consecutively after the applying the first voltage between the first electrode and the second electrode.
