College of media technology, liaocheng university Liaocheng 252059). Abstract: microchip non-contact electrical conductivity detection system is fabricated by microfabrication technology The influence of excitation voltage, excitation frequency and concentration on output signal is investigated Using wewb5.0 software, the simulation circuit of the detection pool was simulated By comparing experiments and simulation results It is found that the two have good consistency It is shown that the analog circuit better reflects the electrical characteristics of the non-contact conductivity detection pool Keywords: microfluidic chip; Non-contact conductivity detection pool; Equivalent circuit simulation Classification no. : O657. 8 literature identification code: A passage number: The Design and simulation of Microfluidic chip with contactless conductivity detection ZHAO Ping1, FU chong-gang1 *, WANG li-xin2 (1. School of chem.and chem.eng., Liaocheng University, Liaocheng, 252059, China; 2. School of Media and Communication Technology, Liaocheng University, Liaocheng, 252059, China) Abstract:A microchip system with contactless conductivity detection (CCD) was manufactured by micro-fabricating technology. A variety of factors affecting output signals such as excitation voltage, excitation frequency and solution concentrations were investigated. The equivalent circuit of the CCD detection cell was simulated using wewb5.0 software. It was found that the experimental and simulation results were in good agreement. The equivalent circuit well represented the electrical characteristics of CCD cell Keywords: Microfluidic
