Paper Abstract

In this paper are presented three optical fiber sensors for carotid pulse wave acquisition. Two probes are based on silica fiber Bragg gratings and the other is intensity-based using plastic optical fibers. Starting with feasibility tests of such measurements with FBG sensors, the sensors evolution was towards a simple method with a lower cost sensor. The sensors were full characterized and some human tests were performed. The results showed a fair compromise between easiness of applicability and technician training, as well as good pressure wave acquisition performance.
