Traditional Chinese medicine pulse diagnosis inherently involves a degree of subjectivity, making it quite challenging to accurately master and apply. It is often said that "the concept is easy to grasp, but the tactile skill is difficult to refine." How to leverage modern scientific and technological advancements to enhance the objectivity of TCM pulse diagnosis, thereby moving beyond issues such as inconsistent standards, difficulty in promotion, and challenges in learning, has become a prominent concern in the research on objectifying pulse diagnosis. Thus, a major aspect of pulse diagnosis research involves using various modern testing technologies and methods to record and analyze the diverse pulse sensations perceived by the fingers.
In recent years, domestic and international studies on radial artery pulse waves have primarily involved placing appropriate sensors on the measurement site to convert pulsations into electrical signals. These signals are then fed into amplification circuits to record subtle physiological and pathological data using recording instruments or computer processing systems. Subsequently, the pulse waves are analyzed for diagnostic purposes.
