Research on respiratory rate monitoring system based on electromagnetic induction self-driven sensor
Respiratory rate is an important parameter of respiratory function,real-time monitoring of respiratory rate is of great significance for the detection and prevention of respiratory diseases.A self-driven respiratory airflow sensor based on electromagnetic induction is designed.The sensor is placed under the mouth/nose to monitor the respiratory rate of the human body by monitoring the changes of respiratory airflow.The sensor has a period of 3.8 s,2.3 s and 1.6 s respectively in slow breathing,normal breathing and rapid breathing,which is less than the human breathing cycle time(3～6 s).The system uses Bluetooth communication technology to transmit data,which is convenient for the test subjects to move.The system realizes stable,real-time and accurate collection of human respiratory rate,which provides certain research value for the prevention and diagnosis of subsequent respiratory diseases.
