Cellulose optical fiber for human health monitoring

    Activity: Talk or presentation types › Conference presentation

    Description

    Cellulose, as a fully renewable, biodegradable, and biocompatible material, creates new possibilities to human health monitoring with optical fiber sensors. Here we demonstrate a face mask that contains regenerated cellulose optical fiber with a 2.2 dB/cm attenuation constant for respiratory rate monitoring. The cellulose fiber inside the face mask rapidly moistens and dries between each breath, which causes a periodic change in optical power transmitted through the fiber. A face mask does not prevent fast drying of the fiber. Cellulose optical fiber length was 3-5 cm with a loop-type sensor structure. Measured respiratory rates varied between 20-40 breaths per minute.
