An ultra-longer tiber cantilever taper for simultaneous measurement of the temperature and relative humidity (RH)with high sensitivities was proposed.The structure was fabricated by using the simple and cost-effective method only including fiber cleaving,splicing,and tapering.The length of the cantilever taper is about 1.5 mm.The dip A and dip B were measured simultaneously,owing to the ultra-long length and super-fine size,the temperature sensitivities of the dip A and dip B reached as high as 127.3 pm/℃ and 0 pm/℃ between 25 ℃ and 50 ℃,and the RH sensitivities are-31.2 pm/％RH and-29.2 pm/％ RH with a broad RH interval ranging from 20％ RH to 70％ RH.Besides,the proposed structure showed good linearity in the sensing process and small temperature crosstalk.It will be found in wide applications in environmental monitoring,food processing,and industries.
