	1	High-performance ZnO humidity sensor synthesized by coprecipitation with PVP as surfactant for human respiration detection显示文摘A high-performance zinc oxide(ZnO)/polyvinylpyrrolidone(PVP)humidity sensor was prepared by simple coprecipitation method with PVP as surfactant.The coprecipitation method has low reaction temperature,little energy consumption and simple preparation,which is suitable for large-scale production.The PVP makes sample’s surface with more hydroxyl and oxygen vacancies than pure ZnO,which can absorb more water molecules and promote the decomposition of water molecules into H3O+to form effective ion conduction.When the molar ratio of PVP to ZnO is 1:1,the ZnO/PVP humidity sensor has low hysteresis(~4.2%),short response/recovery time(9/10 s),excellent stability and high sensitivity with more than 4 orders of magnitude in relative humidity(RH)range from 11%to 95%.Moreover,the ZnO/PVP humidity sensor can distinguish different respiratory states of human body,which has a potential in monitoring and prevention of respiratory diseases.
