Optical fiber sensors in arterial pulse waveform acquisition

摘要

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.
