Wearable device for differential measurement on pulse rate and blood flow

Abstract

A wearable device to measure a user's physiological parameters comprising one or more biosensors, as well as a light source comprising light emitting diodes, lenses for directing light towards tissue of the user comprising blood vessels, and a detection system receiving reflected tissue light. The physiological parameters, for example hypertension, are measured with a differential measurement. For example, the physiological parameters may be associated with pulse rate and blood flow. The output signal is associated with the physiological parameters, and artificial intelligence may be used in making decisions regarding the output signal. Signal-to-noise ratio of the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity, and detecting a change. The wearable device is configured to determine that is being worn by the user and may be configured to communicate with a smartphone or tablet.
