Abstract (en)
[origin: DE19542019C1] Disclosed is a sensor for the non-invasive and continuous measurement of the arterial pulse wave passage time, in which at least two piezo-electric pressure sensors (2) are spaced one behind the other along the longitudinal course (4) of the artery. The invention is characterised by the fact the piezo-electric pressure sensors (2) have a pressure-sensitive strip-shaped surface which in each case is aligned at right angles to the longitudinal course (4) of the artery and in that a housing (1) is provided and has at least two recesses which match the contours of the strip-shaped surfaces (5) and in which the pressure-sensitive strip-shaped surfaces (5) of the pressure sensors are arranged flush with the housing surface.
