Y. Tian and X-Y. Chen
Microfluidic technology is widely used in biology, chemistry, medicine and so on. As one of the important applications of the microfluidic chip, the micromixer plays an important role in the field of chemical analysis. We have studied the influence of the operating parameters of a CO2 laser cutting system on the physical characteristics of the microchannels in a micromixer, observing the speed, power and number of laser processing system. The experimental results show that the depth and width of microchannel increase with the increase of laser power and number. The depth and width of the microchannel decrease with the increase of the speed of the laser processing system.
