Résumé
Objective To acquire high spatial resolution two-dimension pulse pressure distribution for objectifying research of pulse diagnosis in traditional Chinese medicine.Methods A sensor array with flexible packing was designed and implemented.The array was formed on a circle substrate with 37 silicon piezoresistive pressure sensors,which were distributed as equilateral triangles with 1.95 mm pitch.The diameter of the substrate was 15 mm.By using flexible packing,the array had the hardness similar to that of human finger,which made this method closer to the traditional Chinese diagnosis.After differential amplifying,37-way pulse pressure signals were digitalized and reconstructed to obtain the pulse pressure distribution.Results With the application of the sensor array,the pulse pressure signals were measured and transformed into pulse pressure distribution.Conclusions The experimental result contains the relevant characteristics of traditional Chinese pulse diagnosis' description,providing a new way for objective study of traditional Chinese pulse diagnosis and further study.
Résumé
Objective To develop a new,three dimensional dynamic system for pulse detection.Methods According to bionics,a multi-information sensing mode with a soft surface is designed on the basis of traditional Chinese medical diagnosis in pulse.This mode imitates the touching sense of human finger and with the application of modern computer information processing technique,the pulse information is extracted in the way that is as close as possible to the traditional Chinese medicine pulse diagnosis.Results With the application of new sensor,pulse signal is detected and the effectiveness of the inovative three-dimension data transimition mode is validated since the pulse signal is three-dimensionally re-displayed on the computer screen.Conclusion The method introduced in this paper is proved feasible for detecting pulse information.Expected results are obtained and the method provides a new way and new feature reference for research and teaching in objectifying the diagnosis of traditional Chinese medical sciences.
