Abstract	Rapid technological progress has required reliable measurement techniques for velocity field in microspace, particularly in the biochip or electrochemical engineering. Research on the flow in microchannel is the foundation of the microfluidic-based biochip. In this paper, a micro-resolution particle image velocimetry (mu-PIV) system, with order of 1 mum spatial resolution for the measurement of velocity field, was used to measure the pressure-driven flow in the microchannel with barriers. The corresponding numerical simulation was performed as a comparison, and both experimental and numerical results are in good agreement. The results show that the barriers are benefit to the chaotic mixing because of the linked twist maps (LTMs) in these regions. It is important to design an efficient micromixer and to analyze the data collecting from micro-devices
