Pulse Taking by a Piezoelectric Film Sensor via Mode Energy Ratio Analysis Helps Identify Pregnancy Status
IEEE Journal of Biomedical and Health Informatics（2022）
摘要
In order to solve the problem of non-invasive diagnosis and monitoring of women during pregnancy, a piezoelectric film pulse sensing system combined with the mode energy ratio (MER) analysis is utilized to detect human pulses to reveal pregnant conditions. Inspired by traditional Chinese medicine (TCM), pulse diagnosis has a history of more than 2,500 years. The life energy of the human body helps...
