Collision of Microdroplets

The Droplet Collider – Target, Hit, Merge…

Microdroplets ejected by the piezoelectric GeSiM dispensers fly at a speed of about 4 m/s. The high kinetic energy supports mixing of mixable liquids.

The GeSiM Droplet Collider is based on a manual swivel to host two piezoelectric microdispensers. Micrometer calipers allow to adjust position and angle of nozzles to make sure simultaneous ejected drops hit on air.
