1. A system for measuring a blood pressure value of a user, the system comprising:

  • a sensor system configured to be worn on the user'"'"'s body, said sensor system comprising;

    an optical sensor including a light source and a photodetector configured to generate an optical waveform from a signal detected after the light source irradiates a portion of the user'"'"'s body;

    an ECG sensor including at least two electrodes and an ECG circuit and configured to generate an ECG waveform from a first electrical signal detected by a first electrode and a second electrical signal detected by a second electrode; and

    a third sensor that is neither an optical sensor nor an ECG sensor and configured to generate a third waveform from a signal that it detects from the user'"'"'s body; and

    a processor in electrical contact with the optical, ECG, and third sensors, and configured to receive the optical, ECG, and third waveforms, the processor further configured to analyze time-dependent properties of the third waveform determine at least one parameter and to process the at least one parameter and a time delay between at least two of the waveforms to determine a blood pressure value.
