The development of bioinspired olfactory biosensing technology makes it possible to mimic biological olfactory system. To overcome the limitation of olfactory biosensor in sensitivity and specificity, we present a novel olfactory biosensor based on organoid-on-a-chip. 3D culture technique was used to induce mammalian olfactory epithelial stem cells to differentiate into olfactory organoids. After about two weeks culture, olfactory sensory neurons (OSNs) became mature. When the organoids are transferred and fixed to the microelectrode array (MEA) chip and given a specific odor stimulus, the corresponding signal of neural activity is recorded. The feature extraction and pattern recognition of the signal are completed by the neural decoding algorithm, and then the odor recognition model is constructed to realize the high sensitivity, specificity, stability and rapid detection and recognition of the odor. The bioinspired olfactory sensor based on organoid-on-a-chip provides a more accurate and efficient platform for detection of odor.","PeriodicalId":427373,"journal":{"name":"2022 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114644326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of any proposal to cope with this task is partially limited by the characteristics of the sensors employed. Most of the small, low-power sensing devices that are appropriate for mobile robotics suffer from problems like slow response time, long recovery, or low selectivity; and this makes the search process slower and less robust. In this work, we seek to provide a preliminary quantification of the effect of these issues in the results of a state-of-the-art gas source localization method. By using high-fidelity gas dispersion simulations, we compare the behaviour of the robotic agent when attaining measurements from a realistic sensor, with modelled response delay and inaccuracy, versus an idealized one that returns the ground-truth gas concentration value instantly. We find that, for slow-response sensors, there is a clear improvement of the results as the robot is allowed to gather measurements for a longer period of time, giving the sensor time to stabilize. A fast-responding sensor, on the other hand, does not benefit from very long measurement steps, needing only a small time window to account for instantaneous instabilities in the spatial dispersion of the gas.","PeriodicalId":427373,"journal":{"name":"2022 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the main clinical diagnostic methods are invasive tests, and breath test is a non-invasive method for SIBO diagnosis that is more acceptable to patients. In this paper, a smart electronic nose for detecting exhaled breath was designed, which can detect the concentration of hydrogen, methane and hydrogen sulfide in alveolar gas to diagnose human intestinal bacteria. Electronic nose improved the measurement accuracy through chromatographic separation and carbon dioxide synchronous calibration technology. The detection range of hydrogen and methane was 1-180ppm with a resolution of 1ppm, and the detection range of hydrogen sulfide was 0.1ppm-1ppm with a resolution of 0.1ppm. The electronic nose had high repeatability and stability, and can be used for the detection of clinical samples. Besides, the smart data analysis and recognition algorithms had been developed to diagnose the SIBO.","PeriodicalId":427373,"journal":{"name":"2022 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133612524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
