Controlling on-chip droplet two different types of active paper-based micro fluidic chips, open and closed, in which the drop was actively actuated by using an electrowetting phenomenon has been explored. Closed paper chip systems based on parallel-plate devices, and open paper chip systems based on single-plate devices. In case of open paper chip systems, it is possible to droplet transporting, merging and reaction that is already studied. Among the manipulations of droplet, droplet separation and dispensing phenomenon is possible only closed chip systems. It is possible to separated and dispensed droplet that can be operated in the open chip systems in continuously.
In this research was the study of the materials that consist of the closed paper chip system and study for the droplet separation and dispensing phenomenon in morphologically.
