MICROFLUIDIC DETECTION CIRCUIT AND DRIVING METHOD THEREOF, AND MICROFLUIDIC APPARATUS

Title:

MICROFLUIDIC DETECTION CIRCUIT AND DRIVING METHOD THEREOF, AND MICROFLUIDIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2019/205696

Kind Code:

A1

Abstract:

A microfluidic circuit and apparatus for both detecting and driving droplets are provided. The microfluidic circuit includes a detection capacitor (Cc), having a first terminal and a second terminal that are spaced apart from one another to thereby form a space therebetween. The circuit is configured to detect a droplet present in the space by detecting a change of a capacitance value of the detection capacitor (Cc) caused by a change of a dielectric constant between the first terminal and the second terminal, and to drive a formation of an electrical field formed using at least one of the first terminal and the second terminal of the detection capacitor (Cc) to thereby drive the droplet to move in the electrical field.
