dc.description.resumoMolybdenum disulfide (MoS2) is attractive for use in next-generation nanoelectronic devices and exhibits great potential for humiditysensing applications. Herein, MoS2ink was successfully prepared via asimple exfoliation method by sonication. The structural and surfacemorphology of a deposited inkfilm was analyzed by scanning electronmicroscopy (SEM), Raman spectroscopy, and atomic force microscopy(AFM). The aerosol-printed MoS2ink sensor has high sensitivity, with aconductivity increase by 6 orders of magnitude upon relative humidityincrease from 10 to 95% at room temperature. The sensor also has fastresponse/recovery times and excellent repeatability. Possible mechanismsfor the water-induced conductivity increase are discussed. An analyticalmodel that encompasses two ionic conduction regimes, with a percolationtransition to an insulating state below a low humidity threshold, describesthe sensor response successfully. In conclusion, our work provides a low-cost and straightforward strategy for fabricating a high-performance humidity sensor and fundamental insights into the sensing mechanism.pt_BR
