This paper presents a polymer optical fiber (POF) strain sensor for human respiration monitoring. The sensor comprises a POF with notch structure fabricated on a series of extended loops based on flexible elastic substrate. When there is a strain applied on the sensor, the light transmission power changes. The sensors exhibit a large deformation up to 21% and sensitivity about 3. The sensors show high repeatability (less than 3%) and small hysteresis (within 3%). The sensors were demonstrated to acquire the respiratory signals on both chest and abdomen of human body in lying position, which have great potential in breath detecting in nuclear magnetic resonance (NMR) condition.
