The Hong Kong Polytechnic University (PolyU) has made a breakthrough development in optical fibre sensors, making the advanced railway safety monitoring technologies available for medical surveillance inside the human body. The research team led by Professor Hwa-yaw TAM, Chair Professor of Photonics and Head of the Department of Electrical Engineering at PolyU, developed the novel fibre optic microsensors that are biocompatible, supple and extremely sensitive to very small pressure changes inside the human body.
