Portable wireless biomedical temperature monitoring system: Architecture and implementation

This paper demonstrates the design and implementation of a portable embedded system targeting continuous temperature monitoring with wireless interface capability. Our main motive is to provide a solution for monitoring babies´, disable or elderly population body temperature and initiate immediate alarm in case of hazardous cases. Such cases include overheating (fever), under heating, and a high temperature change over a predefined time period. The advantage of the system is its effectiveness as preventive measure against febrile seizures or any other fever condition. The system is extended for interfacing with other devices such as cell phones to enable remote monitoring; an android application to showcase the concept was developed. The system architecture consist of temperature sensors, LCD screen, Bluetooth interface, memory, a sound buzzer all controlled by a single microcontroller core. Even though the system is concentrated on temperature monitoring but the architecture can be expanded to monitor other vital signs like pulse rate, Oxygen saturation or any other interested parameter.
