摘　　要：制备了基于RGO/WS_(2)的LC无源无线湿度传感器,在高湿环境下具有良好的频率响应,其灵敏度最高可达1 560 kHz,且湿敏性能稳定.通过SEM和TEM对反应前后的WS_(2)和RGO进行表征,表征结果为PN结的存在提供了证据.The LC passive wireless humidity sensor was prepared based on RGO/WS_(2).The sensor exhibited good frequency response in high humidity environments.Its highest sensitivity could reach up to 1560 kHz in high humidity environments,and its humidity sensing performance demonstrated high stability.SEM and TEM characterizations of WS_(2) and RGO before and after the reaction provided evidence for the existence of PN junctions.

关 键 词：LC无源无线传感器 湿度传感器 RGO/WS_(2)复合材料
