Analysis and Implementation of non-invasive blood pressure measurement via miniaturised approach

Maximilian Rebhandl

Research output: ThesisMaster's Thesis


This thesis deals with the iterative development of a wearable, non-invasive blood pressure measurement system within the scope of the project CNAP2GO of the company CNSystems (CNSystems Medizintechnik GmbH, Graz, AT). First, suitable concepts for proof of principle are developed, which are then being followed by approaches for miniaturising
the wearable device. Using a fluid system, the pressure is increased in a finger cuff. Adapting the existing CNSystems components enables the simultaneous measurement of light signal derived from pulseplethysmography in order to represent the oscillations of the light signal as an oscillometric envelope. The prototypes aim to be comparable with the currently existing CNAP system, as confirmed by measurement series of a further developed prototype. The precise mechanical miniaturisation of the system for the use as a wearable device is the challenge for future prototypes as the end product, the proof of principle, has been successfully completed in this work.
