摘要：
This work describes a new type of bending sensor based on depressed cladding erbium-doped fiber. Due to the amplification characteristics developed for S-band uses, this sensor has high sensitivity, broad dynamic range, and wide bandwidth. It can be used to monitor static parameters such as force, pressure, displacement, and dynamic parameters used in acoustics and vibration. We describe the sensor characterization in 1490 and 1510 nm in two different conditions: static and dynamic, in frequencies from 25 Hz to 10 kHz.
