High-speed on-chip local flow control by synchronized actuation of piezo-driven dual membrane pumps

We constructed high-speed on-chip local flow control system. The system consists of a microfluidic chip and piezoelectric actuators. The microfluidic chip has microchannels and two membrane pumps. The piezoelectric actuators are set on the membrane pumps, and we can sort cells upward and downward with synchronized actuation of piezo-driven dual membrane pumps. In this research, we demonstrate the on-chip sorting using microbeads.
