Abstract: A microfluidic circuit includes a detection capacitor, 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 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 to thereby drive the droplet to move in the electrical field.
