Miniaturized Olfactory Sensor Chip-based AI-wearable Biometric Ring for Human Body Metabolic Odor Analysis

The source data of the paper titled "Miniaturized Olfactory Sensor Chip-based AI-wearable Biometric Ring for Human Body Metabolic Odor Analysis" accepted in Nature Communications. Update on 2026.05.23: There is a minor typo error of figure 3e when I uploaded the dataset to my Zenodo open repository before the online publication check. I have corrected figure 3e with all the source data in the Nature Communications official publication. Others are the same. Sorry for the inconvenience I have brought to the readers.
