Parallelization of microfluidic droplet generators is one of the major challenges that droplet microfluidics has to overcome to contribute significantly towards the sustainable manufacturing of advanced materials such as nanoparticles, quantum dots, active pharmaceuticals, etc.

A massive parallelization system needs to maintain consistency and uniformity across all droplet makers. To achieve this, we have proposed and simulated a symmetric droplet generator, in which droplet size depends little on the flowing rates and more on the geometry of the device.
