Abstract
A microfluidic system includes a microfluidic chip including a channel layer and a fluid control layer operatively connected to the channel layer, the channel layer having one or more fluid channels. The one or more channels are configured to contain a plurality of droplets. A valve control system is provided to control flow of fluid through the one or more fluid channels in the channel layer. The microfluidic system also includes a droplet impedance detection and feedback control system operatively connected to the valve control system. The droplet impedance detection and feedback control system is configured to detect at least a position of at least one droplet in a fluid channel and to send a signal to the valve control system to operate a particular valve at a particular time based on the detected position of the at least one droplet.
