Research development of temperature and heart rate monitoring based on flexible and wearable medical devices

Body temperature and heart rate are two important parameters of human vital signs. Real-time monitoring of them can provide effective treatment schemes for medical staff. Flexible wearable medical devices have attracted much attention because of their light weight, portability, excellent electrical performance and high integration. This paper analyzes and studies the realization of body temperature and heart rate monitoring by flexible wearable medical devices, gives the principle of measuring body temperature with commonly used flexible thermistor materials and the development of ECG technology for measuring heart rate, points out the challenges faced by accurate measurement, and finally prospects its development trend in the future.
