This paper shows the development of a novel sensor system for the application in the field of diagnostics of blood vessels. In a development project between Fraunhofer IPA and Gutmann Medizinelektronik e.k. an older sensor principle, using quicksilver for the detection of the change of expansion, is replaced by a new sensor concept. The new sensor system uses a combination of fixed and flexible sensor - modules to detect the expansion of the outline of a limb. The core of the sensor system is a hall sensor, which is integrated in a fixed module. In this paper we show the methodic development process of the sensor and the working concept of the final prototype.
