Telemedical human activity monitoring system based on wearable sensors network

The aim of the research is to implement and test a telemedical system to monitor and analyze physiological and movements signals from human. The system incorporates the body central unit (Bluetooth radio, CPU and accelerometer), wearable sensors (ECG, temperature sensor, skin humidity sensor) which are located on the human body, and a mobile computing device to forward data to the remote medical server. The system includes specially designed transmission protocol and remote web-based graphical user interface for real time data analysis. The system was tested on 20 healthy volunteers (15 male, 5 female) during activities of daily living (ADL). Experimental results showed maximum 4% error compared to medical devices and demonstrated the possibility of delivering the telemedical service using data from a remote wearable sensor network.
