A wearable flexible sensor array is proposed to identify body odors. The volunteers ’ body odor are collected and the target gas for sensor testing is obtained by GC-MS. A sensor array is fabricated by using carbon nanotube（ CNT）/organic composite sensitive material. The sensor array is placed in a static test device for single gas test and mixed gas test. Contrast response of sensor array is extracted by using principal component analysis（ PCA） to reduce dimensionality and clustering. The experimental results show that the prepared sensor has 100 %recognition accuracy in static test

which can identify different mixed gas environment and has the potential to be used in human test to identify different human body.
