Document Type and Number:
WIPO Patent Application WO/2024/061373
Kind Code:
A1
Abstract:
Provided in the present disclosure are a digital micro-fluidic apparatus, a driving method therefor, and the use thereof. The digital micro-fluidic apparatus comprises a digital micro-fluidic chip (10), the digital micro-fluidic chip (10) at least comprising a drive electrode (3) and a reference electrode (4), and the reference electrode (4) being configured to write in a first reference voltage. The drive electrode (3) is configured to alternately write in a first scanning voltage and a second scanning voltage so as to be alternately in an actuated state and a non-actuated state. In the actuated state, the drive electrode (3) is configured to actuate composite liquid drops present therein; and in the non-actuated state, the drive electrode (3) is configured to not actuate the composite liquid drops present therein. By means of actuation and non-actuation alternation treatment, the composite liquid drops are treated into target liquid drops, the diameter of the target liquid drops being smaller than the diameter of the composite liquid drops.
