WSN based mobile u-healthcare system with ECG, blood pressure measurement function

A mobile u-healthcare system with multiple physiological signs measurement capability in real time is designed and developed. This system performs local vital sign data analysis using a cellular phone and transmits data over a wireless sensor network. Electrocardiogram (ECG) and blood pressure signals of the patients are continuously be monitored, processed and analyzed locally at cellular phone to produce useful medical information for diagnosis and tracking purposes. When any unknown or suspected patterns of signals are detected, cellular phone performs some simple data analysis first and then immediately transmits these signals to a hospital server for clinicians´ careful diagnosis. Implementation of wireless technology in the diagnosis system enables patient can be monitored anywhere, anytime and would not be impeded by the physical constraints imposed by the cables. This feature could prove helpful in fulfilling the vision of “Pervasive Healthcare”.
