FBG

This is the experimental data of the OFBG-BIWS for underwater applications. The efficient perception of the underwater flow field is of great significance to the development of underwater intelligent equipment. Driven by unique whisker receptors of the harbor seals, this study proposes and demonstrates a bio-inspired whisker sensor based on orthometric Fiber Bragg Grating (OFBG-BIWS). Four FBGs are deployed around an artificial whisker as basic sensing units. The hydrodynamic information is encoded as the wavelength evolution of the FBGs.
