The present invention is based on piezoelectric wearable human body motion breathing monitoring device, method and preparation method of sensing unit thereof. The breathing monitoring device consists of piezoelectric film array breathing sensing sensor, wireless bluetooth type electrical signal processing integrator, air filter breathing mask and flexible electronic wire Composition: The internal structure of the piezoelectric film array breathing sensing sensor is mainly composed of a circular hole groove breathing sensing unit cross array structure, and is composed of a flexible groove array sensing unit, a conductive film, a resin breathing mask belt, a thin airflow filter net and a circular Composition of cross-sectional breathing sensing channels; exercise breathing monitoring method: according to the piezoelectric effect, real-time monitoring of the number of breaths (N) and breathing volume (Q) in the human body during outdoor sports by collecting the voltage signal generated by the piezoelectric sensing array unit in real time to characterize the human body Physiological characteristics during outdoor activities; sensing unit preparation method: Combined with micro-electromechanical system (MEMS) processing technology, the PVDF piezoelectric film array sensing unit is prepared.
Description
Technical field: [0001] The invention relates to a piezoelectric wearable human body movement breathing monitoring device, a method and a preparation method for a sensing unit thereof, belonging to the field of intelligent structures and systems. Background technique: [0002] Breathing is the basic sign of the human body. Especially for athletes, correct and effective breathing rhythm can not only greatly reduce the occurrence of bifurcation, chest tightness and shortness of breath during exercise, but also effectively reduce the unreasonable distribution of physical strength during exercise and increase the alveoli. Ventilation, improve lung ventilation efficiency, and help the human body maintain a stable state. Dr. Nadi Sokolowas, the former director of the National Sports Physiology Department of the United States, and Professor Qiao Yucheng of the School of Physical Education of Shanxi Normal University in China have shown that correct and reasonable ventilation can in...
