Title:
DROPLET GENERATION METHOD BASED ON ELECTROWETTING PHENOMENON, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/103136
Kind Code:
A1
Abstract:
A droplet generation method based on an electrowetting phenomenon, and the application thereof, which relate to the technical field of digital microfluidics. The droplet generation method based on an electrowetting phenomenon comprises: placing a mother droplet in an electrode area on a bottom plate of a digital microfluidic chip, and under a certain electric drive, the mother droplet being ejected outwards to generate a large number of tiny sub-droplets. A relatively large electrode having a relatively large current-carrying area is used, and a mother droplet is placed in an electrode area on a bottom plate, and since the droplet is completely placed in the electrode, an all-directional ejection can be generated. Therefore, the droplet generation method is a rapid, low-power-consumption and high-flux droplet generation method.
