A smart microfluidic system integrated with pressure sensors and flow sensor based on electrochemical impedance methods

We report on a smart microfluidic system with multiple micro sensors integrated in the channel. It consists of a standard PDMS channel, and a smart substrate which has six bubble pressure sensors and a flow sensor all based on electrochemical impedance methods. This system will allow, for the first time, directly and simultaneously monitoring of multiple parameters in the channel of microfluidic systems, including the monitoring of local pressures, flow rate, particles, cells, and so on.
