A novel relative humidity (RH) sensor, based on an in-line microfiber interferometer (MFI), is proposed and demonstrated in an experiment. The microfiber interferometer is fabricated by tapering multi-core fiber down to the micrometer scale in diameter, and the coupling occurs between the center core mode and the multiple side core modes. To enhance the sensing performance, the microfiber sensor is fixed as U-shaped. The variation of RH is monitored by observing the wavelength shift of the transmission spectrum. The experimental resul
