A vital physiological parameter mobile monitoring system for elderly patients in remote areas

Abstract Background The health monitoring situation for elderly patients in remote areas remains challenging. The use of modern computer technology, sensor technology, and mobile communication to provide real-time remote monitoring of vital physiological parameters for elderly patients, especially those with special medical conditions, is highly important. Objective To provide portable and real-time remote monitoring of vital physiological parameters and to increase the level of health care for elderly patients in remote areas, this study designed and implemented an Android application-based remote vital physiological parameter monitoring system. Methods By utilizing the STM32F103RCT6 microcontroller as the central processor and employing microcontroller technology, wireless communication, the MQTT protocol, sensor technology, and Android application development, a user-friendly health monitoring system that enables real-time vital physiological parameter monitoring, and location tracking capabilities is realized. Significance This system can provide alerts for abnormal vital physiological data, effectively responding to sudden emergency health conditions. Additionally, it can serve as a daily tool for monitoring vital physiological parameters, helping to monitor the health of elderly patients in remote areas and improve their quality of life.
