title = "Low cost portable sensor for real-time monitoring of lower back bending",
abstract = "A mechanically robust and compact optical fibre sensor system is described to monitor the bending of the lower back bone in both sagittal and frontal plane. Both bending modes are monitored through the change of the coupled optical intensity ratio between three output fibers aligned to one input fiber. This provides real time feedback when different postures are sustained. The output ratio is calibrated to bending angles using an optical setup that utilized a precise rotational stage. An operation range between -12° to 12° is demonstrated. It is also demonstrated that sensor is suitable for use in a clinical diagnosis system with the additional benefits of being non-invasive, robust, straightforward to use and low cost.",
