Abstract:

According to the problems existing in the prevention and relief of chronic cardiovascular disease in the elderly, a low-power pulse wearable remote monitoring system is designed by combining the PVDF piezoelectric film sensor, GPRS, GPS technology and MSP430 Micro Controller Unit . the structure and functions, the hardware design and the means of wireless communications of the monitoring system, and aim at the actual characteristics of the pulse signal and interference, considering the system power and volume requirements, put forward the corresponding hardware solutions. Experiments results show that the monitoring system has strong anti-interference ability, can get a complete and accurate pulse waveform, has good application prospects.
