This paper proposed a novel three-channel self-pressurized wrist pulse acquisition system based on the principle of wrist pulse diagnosis in Traditional Chinese Medicine (TCM). This proposed acquisition system could not only sample, display, analyze and store the wrist pulses in Cun, Guan and Chi region of the wrist simultaneously under the best pulse taking force, but also simulate the process of wrist pulse diagnosis in TCM clinical science called “three regions and nine pulse takings”. It is believed that this proposed system solved the problem that most of the current pulse acquisition systems could only detect the pulse in Guan region of the wrist. The result shows that the proposed acquisition system provided a user-friendly flexible sample collection platform, laid the foundation for further analysis of multi-channel wrist pulses and pushed forward the development of the standardization of wrist pulse waveforms and the objectification of wrist pulse diagnosis in TCM.
