Oscillometric blood pressure measurements on smartphones using vibrometric force estimation

Oscillometric Blood Pressure Measurements on Smartphones using Vibrometric Force EstimationThis paper proposes a smartphone-based method for measuring blood pressure (BP) using the oscillometric method. To measure BP, it is necessary to measure (1) the pressure applied to the artery and (2) the local blood volume change. This is accomplished by performing an oscillometric measuremen...
