Abstract

Beschreiben wird ein Sensor zum nichtinvasiven und kontinuierlichen Erfassen der arteriellen Pulswellenlaufzeit, bei dem wenigstens zwei piezoelektrische Drucksensoren (2) voneinander beabstandet in Arterienverlaufsrichtung (4) hintereinander angeordnet sind. Die Erfindung zeichnet sich dadurch aus, daß die piezoelektrischen Drucksensoren (2) eine drucksensitive, streifenförmige Öberfläche aufweisen, die jeweils in ihrer Längserstreckung senkrecht zur Arterienverlaufsrichtung (4) angeordnet sind, und daß ein Gehäuse (1) vorgesehen ist, das wenigstens zwei, an die Konturen der streifenförmigen Oberflächen (5) angepaßte Ausnehmungen aufweist, in denen die drucksensitiven, streifenförmigen Oberflächen (5) der Drucksensoren bündig mit der Gehäuseoberfläche angeordnet sind.
