摘要

摘要

En 中文
A microfiber interferometer water hardness sensor is proposed, and its capabilities are demonstrated in an experiment. The sensor is fabricated by using a piece of microfiber with a diameter of 10.4 mu m formed via the heating melt stretching technique. At this scale diameter, a strong evanescent field is generated on the surface of the microfiber, which is very sensitive to the external environmental parameters. Thus, water hardness can be detected by measuring the strength of the interaction between the evanescent field and the concentration of calcium ions (Ca2+) in water. The experimental results show that the microfiber interferometer sensor can accurately detect water hardness. The maximum sensitivity obtained in the experiment is 0.395 nm/(100 mg/L). The proposed sensor exhibits the advantages of easy fabrication, simple structure, cost-effective, fast response and high sensitivity, and has the potential applications in the fields of medicine, biological, chemical, and environmental concentration monitoring.
