ACQUIRING BREATHING MOVEMENT AND HEART RATE FROM INERTIAL MEASUREMENT UNITS

Abstract

Wearable devices can raise suspicion about disorders, so action can taken in a timely fashion. However, wearable devices are still not widespread and inaccessible for many. Using smartphone's and smartwatch's inertial measurement units people's breathing movement and heart rate can be extracted. Breathing movement can be measured by device rotation heart rate can be measured by abdominal vibration. The devices are capable of acquiring signals very similar to Siesmocardiography, Cardiography and slightly similar to Ballistocardiography.
