1. AtGrating (China) AtGrating specializes in Fiber Bragg Grating (FBG) sensors for pressure, strain, temperature, and displacement measurements. They offer customized FBG products, wavelength interrogators, and full technical support including installation, calibration, and repair. Their sensors are widely used in construction, energy, aerospace, and medical applications, and can be embedded in structures for real-time monitoring of pressure and strain . 2. GKER Photonics (China) GKER Photonics produces high-quality optical fiber gratings, including FBGs, long-period gratings (LPGs), and fiber optic interferometers. Their products are designed for precise pressure, strain, temperature, and vibration sensing, and are applied in telecommunications, aerospace, oil and gas, structural health monitoring, and medical equipment. They also provide customized solutions to meet specific application requirements . 3. The Hong Kong Polytechnic University Research Team Researchers at PolyU developed single-ring suspended core fibers for enhanced FBG-based hydrostatic pressure sensing. These fibers feature a central core suspended by a silica ring, enclosed by an outer ring, which significantly improves pressure sensitivity—up to eleven times higher than standard single-mode fibers. This design is particularly suitable for high-precision pressure monitoring in civil engineering, metro systems, and industrial applications .
