1. A blood pressure measurement and monitoring device, the device comprising:
a wearable device;
a tonometry device coupled to the wearable device and configured to compress a superficial temporal artery (STA);
a sensor pad attached to the wearable device and adjacent the tonometry device;
a sensor array integrated within the sensor pad for continuous, unobtrusive blood pressure monitoring, the sensor array having a first pressure sensor that is a testing sensor, and a second pressure sensor that is a reference sensor;
an electric control unit in communication with the sensor array, the electric control unit configured to:
receive first pressure data from the testing sensor;
receive second pressure data from the reference sensor;
correct the first pressure data using the second pressure data to generate a corrected pressure signal;
determine, using the corrected pressure signal, an arterial blood pressure measurement; and
generate a real-time alert based on the arterial blood pressure measurement,
wherein a tissue of the subject includes a testing region and a reference region, the testing region including the STA, and the reference region not including the STA, and
wherein when the sensor array is positioned on the subject, a surface of the testing sensor is configured to contact the testing region and a surface of the reference sensor is configured to contact the reference region.
