Among four diagnostic methods in Traditional Chinese Medicine, pulse diagnosis is a convenient method for diagnosing various diseases. It is based on blood pressure pulse patterns felt by doctor’s three fingers. However, pulse diagnosis is subjective which affects the reliability and repeatability of the diagnosis. Different pulse measurements have been proposed. In this paper, we demonstrate a method to measure wrist pulse using piezoresistive pressure sensor. Experiment results show potential usefulness of the proposed method.
