This paper presents a method to design a detection and processing system for meridian system. In the system, the amplifi cation chips, i.e. AD620 and OP07 are used as the core components to obtain HI-FI pre-amplification. Thus, the very weak signals of the meridian points detected by the detecting electrodes can be amplified. Then, through the filtering circuit, the measuring noise will be suppressed. The filtered signals are sampled as the digital data which will be analyzed by using the Matlab software in the computer. The experimental results show that the good conductivity of the meridian points can be observed clearly. This system will provide a good foundation for further study of the meridian system.
