Abstract:
In order to monitor the physiological condition of the human body in daily life, this study has designed a system of measuring physiological parameters based on cushion, which could detect heart rate and respiration rate when people are sitting. The system can continuously colect signal from cushion with a state of low pressure and without sticking any electrode on people’s bodies. The hardware part mainly includes the signal acquisition circuit of the sensor, microcomputer control module and Bluetooth wireless transmission module. For the two physiological signals have the characteristic of the large noise and low-frequency, we use the Butterworth low-pass filter to process the signal according to an optimized Matlab algorithm. The results show that this system can measure heart rate and respiration rate accurately. Thus, the real-time monitoring on body’s information can be implemented.
