<jats:title>Abstract</jats:title>
<jats:p>An optical-fiber based temperature sensor for the monitoring of breathing behaviour during different physical activities is proposed and demonstrated. The proposed sensor utilizes Fiber Bragg Gratings (FBGs) to detect temperature changes in breath, which are then correlated to the breathing behaviour and thus able to profile the patient for breathing abnormalities. The proposed sensor is cost-effective and light-weight, and can be integrated into wearable devices for real-time monitoring of the patient.</jats:p>
