摘要: Abstract Different sizes of ZnO colloid spheres were coated on quartz crystal microbalance (QCM) by the self-assembly method. The device exhibits excellent humidity sensing properties in whole range from 11% to 95%, such as high sensitivity, good linearity, and fast response/recovery time. results showed that sensitivity these sensors increased with increasing relative (RH). Furthermore, enhanced size spheres. We also discussed adsorption desorption water molecules different humidity.
