In this letter, a novel shrinking long period fiber  grating(S-LPFG) is designed. This strain sensor is fabricated through mechanical polishing and arc-discharging, allowing for certain control over its sensitivity to strain. The single-mode fiber(SMF) is first preprocessed into a D-shaped fiber(DSF) through polishing. Then, a periodic melting-induced shrinking is applied to the fiber through arc-discharging modulation. The polishing and shrinking enhance the asymmetry of the single-mode fiber.

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.

This is the experimental data for the bio-inspired fiber attitude sensor.

High sensitivity optical fiber temperature sensors are extremely important in the domains of biology, medicine, and chemistry. To the best of our knowledge, this paper presents a novel designing framework for high-performing fiber temperature sensors. Photopolymerized-waveguide is embedded in typical Mach-Zehnder interferomenter framework with multimode fiber-single mode fiber-multimode (MSM) structure.
