Drop casting method is employed to coat the PVP and HKUST-1 solutions onto the surface of a quartz crystal microbalance. The resonance frequencies of these sensors with varying relative humidity (RH) from 22% RH to 69% RH are measured using impedance analysis method. The sensitivity, humidity hysteresis, response, and recovery times of these sensors are studied. The sensitivities of uncoated, PVP, and HKUST-1 coated QCM sensors are 7\u2009Hz, 48\u2009Hz, and 720\u2009Hz, respectively, in the range of 22% RH\u201369% RH. The extraction of desorption rate and adsorption energy associated with the adsorption and desorption of water molecules on these surfaces reveals that HKUST-1 has better sensing properties than PVP and uncoated QCM sensors. In this work, the HKUST-1 coated QCM is shown to be a promising material for moisture detection.<\/jats:p>","DOI":"10.1155\/2016\/4902790","type":"journal-article","created":{"date-parts":[[2016,7,31]],"date-time":"2016-07-31T17:03:44Z","timestamp":1469984624000},"page":"1-8","source":"Crossref","is-referenced-by-count":32,"title":["Humidity
