Fibre optic solutions were explored in the acquisition of the pulse wave in the carotid artery, for its morphology analysis and central arterial pressure calculation. Different systems are presented, based on silica fibre Bragg gratings and intensity modulation using plastic optical fibres. The latter solution proved to have the best performance and cost combination. Therefore, it was subjected to a pre-clinical study, comparing its performance with a standard commercial device, in a small cohort of healthy individuals. Having been obtained a very strong correlation between the two techniques,...
