主　　题：human breathing BiOBr nanosheets sonochemical strategy flexible humidity sensor 

摘      要：Flexible humidity sensors are effective portable devices for human respiratory ***,the current pre-paration of sensitive materials need harsh terms and the small production output limits their ***,we report a syn-thesis method of single-crystal BiOBr nanosheets under room temperature and atmospheric pressure based on a sonochemic-al strategy.A flexible humidity sensor enabled by BiOBr nanosheets deliver efficient sensing performance,a high humidity sensit-ivity(Ig/I0=550%)with relative humidity from 40%to 100%,an excellent selectivity,and a detection response/recovery time of 11 and 6 s,*** flexible humidity sensor shows a potential application value as a wearable monitoring device for res-piratory disease prevention and health monitoring.
