PROJECT TITLE :
Body Sensor Network for Mobile Health Monitoring, a Diagnosis and Anticipating System
A system capable of mobile health monitoring was designed and implemented from the first principles. The system is capable of measuring very important physiological parameters, interpret the measured signals, and provide a sense of monitoring and biofeedback to the user. In the case, a medical emergency is detected notifications are sent to a medical tedam for the analysis. The system was designed through the investigation of numerous biosignal extraction strategies. An optical pulse oximeter sensor was designed together with the desired software algorithms. The photoplethysmographic signals were extracted and used to calculate heart rate, saturation of oxygen, and pulse transits time. The pulse transit time was utilized within the estimation of continuous blood pressure measurement. The pulse oximetry implementation applies reflectance-based sensing on the user's fingertip and palm. Skin temperature is also measurable through the use of a digital temperature sensor. The system is capable of providing feedback to the user by means that of a smartphone application receiving data from the device through Bluetooth. The measurement of the proposed physiological parameters were successfully measured with the acceptable degree of accuracy required by medical standards. The system is capable of health monitoring through correct measurements, providing the user with feedback and successfully identifying medical stress ensuing within the sending of a notification to a medical doctor.
