Researchers in Slovenia designed sensor consisting of a thin silica diaphragm created at the tip of the fiber. The central part of the diaphragm is extended into a silica pole, which ends with a round-shaped probe or a sensing cylinder. The entire sensor is made of silica glass and has a cylindrical shape with a length of about 800 µm and a diameter of about 105 µm. Force sensing resolution of about 0.6 µN was demonstrated experimentally while providing an unambiguous sensor measurement range of about 0.6 mN. It overcomes the limitations of force sensors and could be useful for applications from medical systems to manufacturing…read more. TECHNICAL ARTICLE
