Mathematics Modeling and Pulse information Extraction of Visualized Arterial Pulse Detector

In order to obtain the information of pulse diagnosis, an airtight pulse detector with a soft duallayer composite film is developed successfully. The film is painted by the dot grids for the movement analysis. Then the sequence of time-varying pulse image is obtained by using the pulse sensor. The principle of the measurement is modeled, and the feasibility of extracting multidimensional pulse information is discussed. Furthermore, the pulse waveforms are acquired by image processing. And the quantitative analysis is also discussed. The results show that the multidimensional characteristics of the pulse can be effectively detected by using this system, which provide a new approach to the objective and scientific study on the pulse diagnosis.
