Droplet manipulation is of great significance for multidisciplinary researches including life science, materials science, analytical chemistry and engineering thermal management. In 2019, the research on droplet manipulation achieved significant progress in solid-liquid collision, precise manipulation, etc. This paper reviews the research hotspots and representative achievements in the field of droplet behavior control in 2019, including precise regulation of solid-liquid collision, programmable droplet transport and development of a new digital micro-flow control technology.
