Design of Wearable Health Monitoring System Integrating Wireless Technology Based on 3D Graphene Foam Sensor

In this paper, a wearable health monitoring system based on wireless data transmission technology is designed for heart and blood health monitoring. In this system, new three-dimensional (3D) graphene foam sensors are used to capture heart rate signals in real time, and a microprocessor STM32 is used as the main control chip for sending the collected data to the mobile device through low-power Bluetooth. Meanwhile, the blood oxygen and blood pressure data are collected by the mobile device, and then, the acquired physical health data and location information are packaged, stored and sent to the cloud server through 4G communication circuit, so the remote monitoring of the physical health of the subject in real time by the cloud server can be realized.
