A fiber-optic sensor that simultaneously measures relative humidity (RH) and temperature (T) based on a microfiber Sagnac loop (MSL) and MoS 2 nanosheets is proposed. The MSL is made from a microfiber coupler fabricated by hydrogen-oxygen flame heating technology. The sensor responses to RH and T ar...
