Body sensor network for mobile health monitoring, a diagnosis and anticipating system

摘要

A system capable of mobile heath monitoring wasdesigned and implemented from the first principles. The systemis capable of measuring vital physiological parameters, interpretthe measured signals, and provide a sense of monitoring andbiofeedback to the user. In the case, a medical emergencyis detected notifications are sent to a medical team for theanalysis. The system was designed through the investigation ofvarious biosignal extraction methods. An optical pulse oximetersensor was designed along with the required software algorithms.The photoplethysmographic signals were extracted and used tocalculate heart rate, saturation of oxygen, and pulse transits time.The pulse transit time was utilized in the estimation of continuousblood pressure measurement. The pulse oximetry implementationapplies reflectance-based sensing on the user’s fingertip and palm.Skin temperature is also measurable through the use of a digitaltemperature sensor. The system is capable of providing feedbackto the user by means of a smartphone application receiving datafrom the device through Bluetooth. The measurement of theproposed physiological parameters were successfully measuredwith the appropriate degree of accuracy required by medicalstandards. The system is capable of health monitoring throughaccurate measurements, providing the user with feedback andsuccessfully identifying medical stress resulting in the sending ofa notification to a medical doctor.
