摘要:
A humidity sensor is demonstrated using a MoS2-coated etched single-mode fiber (ESMF) and applied in human breath monitoring. Because of the interaction between MoS2 nanosheets and the evanescent field of an ESMF, the light confined within fiber core could be tuned by ambient conditions. The optical frequency conductivity of MoS2 changes with relative humidity variation, so does the transmission light power of the ESMF. A 14 fold enhancement of light power variation in response to human breaths ...More
