Research and challenges of micropumps and microvalves in microfluidic systems

Abstract

Microfluidic chips are driven by microfluidic pumps and controlled by microfluidic valves in microfluidic systems to achieve accurate manipulation of microfluidics. With the continuous improvement of microfluidic chip integration, liquid channels have become more complex and have smaller volumes. How to achieve fluid drive and control at the micro scale has become a key focus in chip design. The paper elaborates on the current research status, key technologies, and development trends of micro pumps and micro valves both domestically and internationally, aiming to provide reference and guidance for the development of related industries and technological research.
