Zusammenfassung:A system, method, and device for monitoring a physiological characteristic of a user includes a wearable monitoring device including one or more LEDs configured to emit light toward a user's skin tissue and two or more sensors laterally disposed along a longitudinal axis of an extremity of a user. Each sensor generates a signal based on an intensity of received light from a location against or adjacent to the sensor where a pulse wave resulting from a user's heart beat passes. A processor calculates one or more physiological characteristics of the user, such as blood pressure or stress, based on the generated signal from each sensor and a lateral distance therebetween.
