MIL-101 is a humidity-sensitive metal-organic framework (MOF) material. In this paper, a balloon-type optical fiber sensor based on the metal-organic framework is proposed, which uses a hybrid structure of fiber Bragg grating (FBG) and balloon-type curved optical fiber, and the humidity-sensitive material (MIL-101) is coated near the geometric center of the balloon-type optical fiber to form a laminated film (LF) structure. When the material absorbs water molecules, its refractive index changes, thus realizing the humidity sensitivity and sensing the temperature using FBG. Based on the above sensing mechanism, the structure realizes the dual parameter detection of temperature and relative humidity. The experimental results show that the fiber optic sensor has a relative humidity sensitivity of 221.6 pm/%RH and a temperature sensitivity of -74.58 pm/℃. This composite structure fiber optic sensor combined with new materials provides good technical conditions for achieving the measurement of ambient temperature and relative humidity.

This research presents a comprehensive study focused on the design, implementation, and analysis of an innovative fiber Bragg grating (FBG) based foot pressure assessment system. FBG sensors strategically placed on the great toe, metatarsal 1, metatarsal 2, and heel provided distinct peak resonant wavelengths, strains, and pressures during experimental cycles. Participant 1 exhibited peak resonant wavelength of 1537.745 nm for great toe, 1537.792 nm for metatarsal 1, 1537.812 nm for metatarsal 2, and 1537.824 nm for heel. Participant 2 showcased distinct graphical representations with peak resonant wavelengths ranging from 1537.903 to 1537.917 nm. In a fracture patient condition, the FBG‐based system monitored weight‐bearing capacity, integrated with real‐time X‐ray imaging for dynamic insights of rehabilitation as distinct approach. The strains and pressures at each position exhibited notable variations along with the sensitivity of 1.31με obtained across all positions, underscoring the FBG‐based system's reliability in capturing subtle foot pressure.
