Sensors, Vol. 19, Pages 4228: All-Fiber Highly Sensitive Bragg Grating Bend Sensor Sensors doi: 10.3390/s19194228 Authors: Oleg V. Butov Alexey P. Bazakutsa Yuri K. Chamorovskiy Artem N. Fedorov Igor’ A. Shevtsov In this paper, we demonstrated a novel, all-fiber highly sensitive bend sensor based on a four-core fiber rod with a diameter of 2.1 mm. We observed a high resolution of the sensor at a level of 3.6 × 10−3 m−1. Such a sensor design can be used in harsh environments due to the relatively small size and all-fiber configuration, containing no adhesive, nor welded joints.
