DROPLET SEPARATION DEVICE, SEPARATION SIGNAL GENERATION DEVICE, SEPARATION SIGNAL GENERATION METHOD, AND PROGRAM

WIPO Patent Application WO/2024/096137

A1

This droplet separation device comprises: an upstream part; a chamber part provided downstream from the upstream part and having a larger cross-sectional area than the upstream part; a branch part provided downstream from the chamber part; two branch flow paths branched by the branch part; a micro flow path in which droplets flow together with a first fluid; a droplet interval adjustment flow path that is connected to the upstream part so as to flow thereinto and causes a second fluid having the same composition as the first fluid to flow into the upstream part; an electric field generating electrode that is provided adjacent to the chamber part and that generates an electric field by applying a voltage controlled by an external signal; and a plurality of reference electrodes provided to generate an electric field gradient in the chamber part in response to the generation of the electric field by the electric field generating electrode, wherein the branch part has an asymmetric shape so that the droplet flows into only one of the two branch flow paths without being broken when the electric field generating electrode does not generate an electric field.
