Wearable FBG Sensor System for Respiratory Strain Measurement During Daily Activities

Popis výsledku v původním jazyce

This study developed a wearable fiber Bragggrating (FBG) sensor system and explored the measurement of respiratory rate during daily activities of life such as standing, walking, and running. The measurement systemused was a wearable FBG interrogator that we developedourselves. An FBG sensor, which is an optical fiber-typestrain sensor, was installed on the inner surface of the belt,and this belt was wrapped around the body. The respiratory cycle calculated from the respiratory strain signal measuredby the FBG sensor was almost identical to the reference respiratory cycle measured by the temperature sensor. Initially, the pressure applied by the belt was found to causedi s comfort over prolonged use. This issue was resolved by further refining the belt shape. Respiratory strain was almost accurately measured with the improved belt even when the following daily activities occurred: standing, walking at4 km/h, and running at 10 km/h. In addition, it provided a high S/N ratio respiratory strain signal even when participants were asked to walk in a hallway and upstair and downstair. The sensor system developed in this study can help measurerespiratory rate in daily life without interference.
