Abstract: Increasing life expectancy accompanied with decreasing dependency ratio in developed countries calls for new solutions to support independent living of the elderly. Ubiquitous computing technologies can be used to provide better solutions for healthcare of elderly person at home or hospital. Also, data fusion from multiple sensors shows itself the capability to have better monitoring of person. In this paper work, the healthcare parameters as like ECG and accelerometer are used to give a better treatment to the elderly person at home or hospital. Accumulated vital signs data through long-term monitoring is a valuable resource to assess personal health status and predict potential risk factors through the fusion monitoring of multiple sensors. The hardware allows data to be transmitted wirelessly from on-body sensors to a base station attached to server PC using IEEE802.15.4. If any abnormality occurs at server then the alarm condition sends to the doctor’s personal digital assistant (PDA). The system provides an application for recording activities, events and potentially important medical symptoms.


Keywords: ECG, Accelerometer, QRS-Complex, P-wave, T-wave, Acceleration norm, Orientation angle, Ubiquitous healthcare
