System and method for cuff-less blood pressure monitoring

A wearable blood-pressure monitoring device comprising:

• a controller;
• a plurality of pairs of electrodes arranged to be in contact with a bodily region of a wearer;
• a plurality of pairs of sensors coupled to the controller, each sensor of the plurality of pairs of sensors being positioned in contact with the bodily region of the wearer and interposed between a pair of electrodes of the plurality of pairs of electrodes;
• and
• a securement device coupled to the controller.

A method of calibrating a wearable blood-pressure monitoring device, the method comprising:

• receiving a plurality of pulse observations from a plurality of sensors disposed on a blood-pressure monitoring device, the blood-pressure monitoring device being arranged on a bodily region of a wearer;
• capturing signals from different combinations of sensors of the plurality of sensors;
• determining a subset of sensors of the plurality of sensors that provide data actionable for a determination of pulse wave velocity and other important physiological parameters;
• and
• measuring pulse wave velocity as a phase shift between the subset of sensors of the plurality of sensors.
