The potential impact of optical fibre sensors embedded into medical textiles for the continuous monitoring of the patient during Magnetic Resonance Imaging (MRI) is presented. In that way, we report on several pure optical sensing technologies for pulse oximetry and respiratory movements monitoring. The technique for pulse oximetry measurement is known as NIRS (Near Infra-Red Spectroscopy) in a reflectance mode. In parallel, we tested two different optical sensor based fabric designs breathing activity detection – a macro bending sensor and a fibre Bragg grating sensor consisting in respiratory frequency measurement by intensity variation detection and optical spectral analysis.
