A wireless body sensor network platform to measure vital signs in clinical monitoring

Medical applications and clinical environments set new demands on sensor network technologies, one of the key research areas in computer science and health telemonitoring. This paper presents a wireless systematic architecture, a hardware and software platform based on low-power integrated circuits, on-chip signal processing components and communications. The structure of such architecture consists of lightweight miniature nodes placed strategically on patients to allow non-invasive, continuous and ambulatory health monitoring and inexpensive, to provide medical readings on local devices and clinical records applications on web browsers and mobile devices. The main goal of this project is the development of an autonomous wireless monitoring system for vital signs with battery-powered nodes and medical sensors. It acquires, stores and transmits signals to determine the states of oxygenation, heart and respiratory rates, and temperature in real time to a central monitoring station, that integrates a touchscreen graphical interface and mini-OLED displays. This work provides self-monitored environments minimizing the requirements for primary needs, early medical attention, optimizing premature diagnosis and comfort of patients, through a set of algorithms that contribute to the performance of the nodes generating significant benefits on human lifetime through early disease detection.
