利用光纤的大弯曲损耗效应，研制了一种用于无创呼吸监测的胸腹围测量传感器。新型传感器采用新颖的8字形回路配置，增加了响应的线性度，减少了机械阻力和滞后，以及其他优点。对新型传感器在呼吸监测中的应用性能进行了测试，结果表明，新型传感器在分辨率和灵敏度上均优于传统传感器。这种增强的性能使得使用相同的转导纤维测量呼吸和心脏功能成为可能。
The macro-bending loss effect in optical fibres has been used to redevelop a sensor for the measurement of thoracic and abdominal circumferences in non-invasive respiratory monitoring. The new sensor uses a novel figure-of-eight loop configuration, which results in increased linearity of response, less mechanical resistance and hysteresis, as well as other benefits. The performance of the new sensor as applied to respiratory monitoring is examined, and indicates a higher resolution and sensitivity than the old. This enhanced performance enables measurement of respiratory and cardiac function using the same transducing fibre.
