About

Dr. Rui‐jie Tong is a leading innovator in the field of fiber-optic sensing technology, with a specific focus on advanced Fabry–Pérot interferometer (FPI) sensors. His most-cited work, "Optical fiber axial contact force sensor based on bubble-expanded Fabry–Pérot interferometer" (2018, 17 citations), represents a significant breakthrough in micro-force measurement. In this study, Dr. Tong pioneered a novel sensor design that utilizes a bubble-expanded cavity within an optical fiber, dramatically enhancing sensitivity and enabling precise axial contact force detection. This contribution addresses a critical gap in minimally invasive surgical tools and robotic tactile sensing, where accurate, real-time force feedback is essential. By leveraging the inherent advantages of fiber optics—such as immunity to electromagnetic interference and compact size—his sensor offers a robust, high-resolution solution for demanding environments. Dr. Tong’s work has been widely recognized for its practical impact, with his 2018 paper serving as a foundational reference for subsequent research in optical micro-sensors. His ongoing efforts continue to push the boundaries of photonic sensing, inspiring new generations of engineers and scientists to explore the potential of fiber-optic technologies in biomedical and industrial applications.
