In this work, a new optical fiber Bragg sensor for hemodynamic assessment, whose main goal is to acquire the carotid pressure wave, is discussed. The sensor implies a unique fiber Bragg grating and uses the distention and contraction movements of the carotid artery to strain the grating and detect the arterial pressure waveform. Some preliminary data acquired in a human subject carotid are presented. Finally, it is discussed the potential impact of the Bragg
technology, and this particular sensor, on physics teaching in engineering education and future projects.
