Abstract:
We demonstrate an ultrafast humidity micro-fiber sensor based on molybdenum disulfide (MoS 2 ) cladding with three dimensional network structure. The high surface-to-volume rations and porous mesh structure improve the interaction of between MoS 2 and water molecules, further enhancing the performance of the humidity sensor. The results demonstrated that the sensor can perform in a wide relative humidity (RH) range between 10%RH to 90%RH with rapid dynamic behavior (response and recovery time are 0.090 and 0.130 s respectively). The sum of response and recovery time (total time) is 0.220 s, which is the fastest in the reported MoS 2 -based humidity sensors. The sensitivity of this sensor is up to -1.501 dB/%RH in the RH range (77%RH–90%RH). Such a high performance RH sensor will have a wide range of application potential in chemical processing, various medical diagnostics, and so on.
