About

Dr. Xiangrui Ji is a pioneering researcher at the forefront of flexible electronics and intelligent sensing systems, with a core focus on developing high-performance tactile sensors for next-generation human-machine interfaces. Their most notable contribution is the invention of an iontronic capacitance-enhanced flexible three-dimensional force sensor, which achieves ultrahigh sensitivity by leveraging electric double-layer effects at microstructured interfaces. This breakthrough, detailed in their highly cited 2023 paper (25 citations), directly addresses the longstanding challenge of simultaneously achieving high sensitivity and effective signal decoupling in flexible 3D force sensors—a critical need for advanced robotics and machine-sensing interfaces. By enabling precise detection of both normal and shear forces with exceptional resolution, Dr. Ji’s work has laid the foundation for more intuitive prosthetic control, dexterous robotic manipulation, and immersive virtual reality feedback. Their research elegantly bridges materials science, microengineering, and signal processing, offering a scalable pathway to integrate tactile intelligence into soft robotics and wearable electronics. Dr. Ji’s contributions are shaping the future of how machines perceive and interact with their physical environment.
