1. A method for continuously, non-invasively, and directly measuring blood pressure, the method comprising:
providing a calibrated measurement device having a frame with a first side and a second side, a balloon mounted to the second side, an optical system between the first side and the balloon, and a sensor array having a sensor surface;
placing the sensor array in a non-invasive manner over a skin surface connected to an artery by adjoining soft tissues;
inflating the balloon with a controlled amount of pressure;
in response to the inflating of the balloon, detecting signals, via the optical system and the sensor array, caused by changes in artery size and shape during a heartbeat cycle; and
measuring and processing, via a controller, the signals to determine blood-pressure parameters.
