Abstract
A sensor device or system for performing a blood pressure measurement comprises a finger abutment surface, a first sensor operative to sense blood volume pulses in a finger pressed on the finger abutment surface, a second sensor operative to sense a force or pressure with which the finger is pressed on the finger abutment surface, and processing circuitry operative to process amplitudes of the sensed blood volume pulses and the sensed force or pressure with which the finger is pressed on the finger abutment surface to determine an absolute blood pressure.
